Deltaaquarium Reviews 

I would not recommend this company, my order came with dead fish tried to contact no answer at all within the day rest of fish delivered died
i left what's app message as states on delivery form and pics of dead fish still no response.

Most fish are ok, but 4 angel fish died, and my tank now has whitespot, which i can only assume come with the new fish. I have contacted them, as they have some "guarantee" but have had no reply

All six fish were dead on arrival, the shrimp barely alive and very small, I also lost those within days. Managed to get a partial refund but would never order from them again. Very disappointing.

Order #113539] (June 20, 2025)

Ordered 50 Cardinal tetras, they arrived on the specified day, all but 3 were dead. They had been packed in very little water in one bag. The remaining 3 died the following day. Delta politely and apologetically offered to send a replacement order, which arrived on the 3 July. Since then 17 have died. All were in a well established, heavily planted 500 litre aquarium with some existing shrimp and Corydoras. I’m afraid to say I would avoid this company at all costs, as helpful as they were in sending replacements, it doesn’t excuse they appalling quality and poorly trained staff that allowed them to ship out in such an unacceptable manner.

After ordering then checking the reviews was a bit worried about what would happen, ordered early Thursday morning, recieved following Thursday, rang the store (angel aquatics) answered and updated everytime, mishap with the order (made another order for collection to get sent with order as stated on website) didn't get sent with original delivery order but when I rang and spoke to then they offered to send them out or offered a refund, took the option for a refund and it was issued about 40 mins later after the call, recieved all fish (about 25) an all but one are fine swimming round in their new tamk tank, overall good experience would order again

This was my first time ordering fish online, so I wasn't sure what to expect. I certainly didn't expect all 10 to arrive happy, healthy and raring to go! I took my time to acclimate them (1.5 hours) to get them used to temp and water etc (I have a tannin level I wasn't sure they were used as well), but also to the movements of my lively dojos who are peaceful but very inquisitive. I ordered 5 gold and 5 regular minnows. They came in two separate bags but I merged them before releasing so they could start shoaling. Within an hour they were eating still in the bag, and showing more interest than fear in the dojos, and digging at the bag to be released. All 10 of them are healthy, bright, confident fish. If anything goes wrong now it's on me. The only thing I would advise if buying - expect to wait at least a week before hearing about delivery. If you're impatient, visit your local aquarium.

AVOID-They like to lie too.
Awful place, sent 4 live fish out of 5, the fish all died that night and the next day the beta fish I already had died too. The water stank as well an hour after I put the new fish in.
No refund as it was after 3 hours.
Tried emailing them sat, they claim they didn't get it.

Edit: I received a phone call where I was essentially blamed, told off for writing an online review, told to remove any and all negative reviews, told he "might try" to get me a refund anyway, then received an email from management saying I won't get a refund and I was "disrespectful" to staff.
I wasn't, I was snappy, but he started off very hostile, admitted he likely wasn't going to refund me so I told him not to call up to just harass me. Which he took great offence to.
At no point did I raise my voice or swear like they're now claiming.
My fish died cos of these disingenuous people.
Avoid at all costs.

Edit 2: Hours later gone 10pm, I get nasty emails and find an Instagram message telling me again that I swore at them on the phone (Again, I did not.) and that my problems had "Nothing to do with them" It's "impossible for fish to die after 3 hours" and that people like me "should not keep anything alive."

A partial refund of the one DOA fish (94p) and an email telling me I'm disrespectful and shouldn't threaten to post things online.

I did email them yesterday that I'll post online as I was upset over my fish dying from their gross dying fish, as I HAD tried to reach them days ago, with NO reply.

I hope they'll enjoy the money they got from me and the sense of satisfaction they obviously get from being crybullies and liars.

I also hope they leave me alone now.

Edit 3: Another email from them at almost 11pm after I've twice told them to stop contacting me. I've blocked them.

Again, avoid this shop and these nasty people.

I recently brought a Red Belly sideneck Turtle and 5 X Bumblebee Gobies I received fantastic customer service,there was an issue with the delivery who said I was out when they tried to deliver I was obviously in I tried to call the delivery company yet it was just the automated service so I called Delta who with in less than an hour had managed to get the delivery company to turn around and actually deliver my parcel.They were fantastic with out there help I would not be looking at perfectly healthy fish and a fantastic Turtle.They were packed very securely with plenty of heat packs I shall definitely be buying from Delta Aquariums in the future

Excellent place to buy fish the staff ie Kane an mendez and Mike were Excellent and know everything about fish and very helpful and price's are very good and great place to buy fish so give it a try you won't be disappointed 5 star service and fish 😀

this is the second time i have used deltaaquarium to purchase fish, this order a large one costing 124 pounds have to say there was good communication and prompt delivery and all fish arrived in good condition, will use again at some point and will recommend to friends. thank you for your service

Avoid at all costs! Sending delivery with dead fishes and trying to avoid refund. How such a company can exist at all? Who is regulating such companies who are making those little fishes dead. Horrible experience and fells sorry for those fishes and waste of money.

My experience with Delta Aquarium has been extremely disappointing. I ordered 20 shrimp (10 Amano and 10 yellow Neocaridina) along with shrimp food.

Unfortunately, the shrimp arrived partially frozen (in very cold water). The 10 Neocaridina were divided into two bags: one contained 3 adults, one of which was dead, and the other two died shortly after, likely due to the cold. The second bag held 7 tiny shrimp, including 1 red and 1 white. Not wanting to mix the species, this posed a problem for me.

Additionally, the shrimp food was missing. It took me a month to receive a refund, but they only reimbursed me for the food, excluding the dead and incorrect shrimp. Before writing this review, I attempted to contact them again to request a refund for at least 3 shrimp, but to date, I have received no response; they are completely ignoring me. I will purchase shrimp from another seller and strongly advise against using Delta Aquarium.

AVOID AT ALL COSTS.

After a few days I had 1 fish and 1 frog die from this place.

And of course the seller is trying to put the blame on me.

I have had fish for years with no issues I even breed many different ones and have no issues. I check my water regularly too and it always reads good.

The communication from this place is absolutely shocking. Takes forever to get through by phone or text or even WhatsApp.

I've had to go through the payment provider to try and sort this issue as the seller disnt seem one bit bothered about it. Just trying to blame myself.

Upon reading the reviews I can see now I should have gone elsewhere as I see alot of people having the same issues with this place. Quick enough to take your money but don't care when there's an issue.

Like I said avoid at all costs.

What a shame. From reading previous reviews it would appear that the Store is Fine to visit but this Company should not be offering a mail order service. I have tried to purchase from them and given up! Not being local I had no choice by mail order. I telephoned to check stock and also cost of other items. Spoke to Laura (who was working from home). she took detail and promised to call back. No call ever received so tried emailing, also remained unanswered. !! How can they expect people to purchase from them if they can't even do a simple thing like this! Thank goodness I didn't buy anything! Caveat. Emptor!!!!

Three fish were doa, not just dead but furry with mould, they must have been put in the bag dead. these were refunded which is good, but out of my order 11 other fishes were completly missing and i am having trouble getting anyone to even answer emails about this let alone refund me for them. avoid.

I placed an order for some fish on 20/01/2025 but after initial order confirmation, I heard nothing back about delivery and was unable to get a reply via email or phone (their mailbox is full so couldn't leave a voicemail either) until 29/01/2025 when I finally got a response after messaging on Instagram.

I was told that they had been busy dealing with back orders and it was suggested I should communicate via email on WhatsApp as these are monitored daily. Delivery was eventually scheduled for 31/01/2025 and I did receive this, but the 10 rummy nose tetra id ordered (amongst other things) arrived dead or dying.

I messaged via WhatsApp as advised but this message remains unread on 07/02/2025. After further chasing and more emails, I finally received a refund for the cost of the rummy nose on 04/02/2025.

I can see from reviews that I'm not the first to be disappointed but feel really let down by this company, who take your money (over £100 in my case), offer little to no communication following order placement, deliver late and supply sub standard (dead or dying) fish.

Avoid at all costs.

Absolutely not impressed with the service or the quality of the poor fish. Ordered on the 12/1/24 delivered on the 29/1/25, well the box was ok, but the heat pads were at the top of the box and basically cold, so fish were cold.
Double bagged ok. Sadly within hours the fish began to show signs of ICK, I immediately treated. 2/2/25 know only 3 fish alive from 16, but the ICK seems to be clearing.
I am not new to aquariums and have bought most of my fish, shrimps and snails through the post. No issues!
Sorry but I definitely CANNOT recommend this place for fish.

Absolute Jokers!

Where to begin with these? So I ordered over £120 worth of stock and 4 out of the 14 I ordered have died within 3 days, it could probably be down to the delivery driver just literally dropping the box on the floor when delivered. I even asked him if he knew live fish were in the box to which he fully acknowledged. The delivery time was horrendous and when they say you’ll get a 2 hour time slot you only get this like 30 minutes before hand. It’s a joke but not the biggest one.

The biggest joke was when I ordered 4 Blood Red Juwel fish (clue to the colour is in the name) and they’ve sent me something completely different?? I’m still trying to figure out what they are but they’re certainly not Blood Red’s they’re not even Red, they’re white for Christ sake! These folk don’t know their species at all and the photos online I suspect are taken from someone else’s website.

I’m so glad I only ordered a few as I wanted to overstock two 240 litre tanks but it won’t be from these. It’ll be from somewhere that knows their fish. To make it worse the fish that died aren’t one of the unidentifiable ones. I’m going to my local fish shop within the next week with photos to try to identify them and I’ll update this review when I finally can.

Just a word of advice, if you haven’t ordered from these before I’d give them a serve.
