Which species of fish can i choose from to live in 6 Gallon Aquarium?

Question

I hope to have more than just one type of fish. The tank is only 6 gallons, so I know I'm limited in choices. I'm looking for particularly easy to care but active fishes (less idling and more movement)

Answer 1

I have a 6 gallon eclipse system, it has been cycled fully from the 2nd month on, so it is not very difficult to establish a biological filter. It had a fan tail gold fish in it when he was a baby, he grew out of the tank in 5 months, but he is in a 30gal with another fantail now. I have kept guppies, only 3 really fit, they did not last very long, come to find out, they had a bad batch at the pet store, currently I keep...zebra danio(4) and ghost shimp(4) they seem to be having a harmonious relationship, the tank is a little overstocked, but I stay on top of tank maintenence, I do a 45% water change about every 4-5 days. If you keep fewer fish you will have less maintenece, once you get the tank fully cycled. You could try a school (6) of small tetras like neons or black tetras, but they are very delicate & will not like the cycling process. They die very quickly from ammonia poisioning. So avoid these untill the tank is well established. Most of the fish you can keep in a tank that size are schooling fish, and require a few brethren to feel at ease. Or if you just want one big showy fish, a Beta Splendens with a bunch of java moss with an apple snail, and a ramshorn snail would look pretty neat in the 6 gal.
good luck

Answer 2

If your tank is freshwater, you have lots of options. Goldfish (the standard), guppies (they can reproduce if you get a male and female), Gouramis (they will get big though), danios, or cichlids would work. Just make sure that the fish that you choose are compatible. Community fish with community fish. Aggressive with aggressive. Otherwise someone will become lunch. If you are confused about types, do some research online or visit your local fish store and look at fish. Usually a good fish store will have descriptions and info about nature of the fish on the tanks. Ask lots of question too!
If you trying to start a saltwater/ marine tank, 6 gallons is definately too small. Need at least 30 gallons for those.

Happy fishing!

Answer 3

6 gallons is awfully small for a fish tank. It is very difficult to get a good biological filtration system started in such a small tank. But since you have the tank already something hardy like a Platy or swordtail would be good. Lot's of people recommend mollies, but personally I've had little to no success with them.

Some other good fish would be Gouramis (I would only recommend 2-3 of the dwarf varieties) and they are labyrinth fish and therefor do not need an aeration system.

Other good fish... well there is the goldfish, but with the heavy inbreeding they are not the hardy fish they were then years ago. Tetras are good too. I like the red skirt tetra a lot.

I hope this helps. Just stay with community fish. Also look to your different pet stores. Some have a 10 day or 14 day guarantee if your fish dies in that time frame. Transporting is very stressful on fish and even with the best of care the shock and stress of traveling in plastic bags get the better of them.

Answer 4

You can have a nice group of 5 small scooling fish. Try something interesting like a school Longfin Blue Danio, Black Neon Tetra, or a pair of gouramis. Maybe 4-5 fancy guppies, but you will have to watch out, they will outbreed that quickly.

Answer 5

Goldfish are definitely out, they will die in such a small tank. You can get a female betta, or two, as long as their temperments are nice, and house them with a couple of cute African dwarf frogs. Look for fish that grow no longer than an inch, and you can probably get as many as five or six, as long as you have a filter and keep the tank clean. Good luck!

Answer 6

Try putting a betta inside. Maybe put a couple of neon tetras with him. Be creative. Also consult your pet shop as to what they think is a suitable fish for your tank.
