I have 2 of these tanks so far & found them great.
I have a Beta in each & they love it. The lid concerned me at 1'st but once I made legs for each corner it was fine. I just stacked self-adhesive little squares (that I got at the dollar store), until I got a desired height & problem solved--breathing space.

Pros: easy to clean, sturdy, easy to install

I had a filter, heater, gravel, and decor. I only needed an aquarium that my filter would fit in. So I came across this Marineland 2.5 aquarium.
This aquarium works out BRILLIANTLY for me and my Betta. He does have enough room, so I bought him a snail companion. They seem to like it, and so do I!

This aquarium is only good if you don't want a lid, the dividers, or a hood light because you cannot get them in the store and if you try and order them from the website they give you they do not have them. The only way to buy them is to go through google and find a place selling them but if you want them plan on paying what you paid for the tank thanks to their HIGH shipping costs. Just to get two dividers is at least $13..

I've had this aquarium for about 6 months for one of my bettas and it works well-only because I had the lid modified. The glass lid comes with NO HOLES for air. This means whatever lives in it will get no air with the lid on. I paid to have a glass cutter cut a hole for air in the lid and cut out one of the corners for a filter. I just sit a light on top of it. The glass cutting cost $35.00. Finding a lighting hood for this tank will be very difficult. You can buy a clip-on light, but the lid won't fit right with the light clipped on. If you want a proper home for a fish or any other animal, you're better off buying something else, unless you plan on keeping the top open. Also, this tank is rated at 2.5 gallons. It actually holds just under 2 gallons with my substrate and decorations in it as pictured.

I bought this aquarim to provide more space for my mangroves to grow and is great with some White Cloud Mountain Minnows I added. It is not too small like a fish bowl, but is not too big so it fits well on a desktop. A small filter would be a necessary purchase for tropical fish. The aquarium itself is sharp and well built with crystal clear glass. You won't be dissappointed if you're looking for a small aquarium for a few fish.

I initially bought this tank for my 2 African Dwarf Frogs but as they got more and more active, it didn't seem like they had enough room. They were upgraded to a 10 gallon tank with a few platy roommates. Little did I know that platy breed more than rabbits. I set this tank up again and now use it as my nursery. It is perfect for the fry. It is also great to keep as a quarantine tank. I only keep a floating plastic plant, 3 small rocks, marimo (moss) ball, and a rock / cave decoration in it. I don't have any gravel in it because the babies hide in it and that makes it difficult to clean. I have a Marina 10W heater with it, which keeps the fry comfortable; and a Tetra Whisper 3i filter. I don't turn the filter on, and only leave it there to help keep the tank cycled. With all that in there, there is till plenty of room for the little ones to swim! Thinking about getting another one for my Betta fish at work!

excellent for bettas

December 10, 2012

These have been great for my two bettas, who each have their own little home. I think they're much happier and healthier than they would be in cramped bowls! The tanks are large enough to be suitable for an appropriate mini-heater, which is a necessity in my cold house, but also small enough to be super easy to clean. Even doing a full water change for both tanks is pretty fast and easy.

I agree that the glass top doesn't breathe very well, but I've gotten around that by leaving a small gap at the back, too small for my fish to jump through but enough to allow for some airflow. It's also far easier to clean than a hood.

I'd highly recommend this for bettas or small fish that might like some room but don't need huge tanks (definitely NOT suitable for goldfish!) Excellent product.

I have several of these tanks and I find them to be PERFECT for quarantine tanks for my African Cichlids as well as for raising the fry (babies). I have raised hundreds of Cichlids in these and they always turn out so healthy and strong since I also have a Whisper filter in them to keep the water moving and help them get stronger. HIGHLY RECOMMENDED!

I love this little tank. I'm a big advocator for larger betta tanks, and I think 2.5 gallons really should be the standard size for a betta. I really like that is a very useable design, and you can customize what you want in it. I have 2 of them for different bettas. One I have a TOM mini internal filter in (which works great) and both have hydor theo 25w heaters.
I'd definitely recommend this tank to a new betta owner. It is possible not to filter it if you are consistant with regular water changes, and it gives a betta enough room to stretch its fins. Great deal for the money.

I dont actually own any fish-so i don't know which ones this would be appropriate for. What i can tell you is that its the perfect size for African Dwarf Frogs. They are so happy in it. I put plants, a rock hide thing, river stones, and a snail. They swim and hide. This is the best size for them since if they have too much depth or space they can actually drown. Five stars!

My betta, Hibiscus loves this tank. He is constantly swimming around in it. I have put some plants and decorations in it and it fits on my dresser/shelf/table or practically anywhere. It is big enough for hibiscus to swim around in big circles, and to dive down and swim back up,so he loves having this much space. The tank has never leaked, like my old one, and also wasn't too expensive. It looks really nice and you can decorate it beautifully, and is nice and big but at the same time not too bulky and heavy. This is a great tank to get your betta or any other fish!

Pros: easy to install, easy to clean, sturdy

i got this tank a few months back for my betta, Trigger. he was in a 1/2 gallon but when i moved him in to the tank he flourished! his color looked better and he was overall healthier.
the top has never been an issue with me. (Trigger seems to breathe just fine)
and the weight is a little heavy but its still a lot easier to clean out than my 10 gal!

Pros: easy to install, easy to clean, sturdy

I purchased this tank for my Beta fish. He LOVES it. There is more than enough room for him to swim around, along with space for his rock cave and 2 plants. I couldn't be happier and recommend this tank 100%.

If you're looking for a small tank for a betta, dwarf frog, or maybe a couple of shrimp this is perfect. Yes a 10gal is available for the same price, however, this one is the perfect size for a desktop, bookshelf, etc. The lid is a tight fit, not good for labyrinth fish (such as Bettas) if you keep water filled to the top. Also the lid doesn't allow room for filter, heater, or cords. I've kept my lid off for this reason (decor is tall + heater & cord) and it works just fine. Perfect desktop tank

Pros: easy to clean, sturdy, easy to install
