CichlidFish.com - Fish That Think.

snice i ve moved my O's into the 55gal my 20gal is empty what type of fish will do in there and how many. Maybe something with some color or something that can be entertaining?

There's a zillion species that will fit the bill -- I'd go livebearers for an empty 20. Mollies, Guppies, Platys, etc. Very colorful, stay small, and are a joy to watch and keep. --Mark

i agree, anything that gets bigger then you'll be looking for another big tank, i have a friend that raises fan tail guppies and they are gorgeous. i would go to your local fish stores and just look around to see what they have that peaks your interest, if your like me, they all will.

I have guppies and i have found that they like some aquarium salt in their water, about l tablespoon per one gallon.  There are many varieties and move around alot, though they are supceptable to fin rot.

You could go with one Beta which is usually not aggressive with non-Betas, unless they look like a Beta, and I personally like mollies to go with it.  A couple silver, a couple dalmatian, a couple black.  To me that would be a nice 20 gal. 

The silver molly is very bright, the black molly is very dark, and the dalmatian is a nice mix of both and can have either a black base or silver base with opposite spots that can be anywhere from lightly to heavily spotted.  This to me would provide contrast (that is to me, colorful in itself) and a school of fish, that would make the vibrant colors and finnage of a nice beta stand out even more, being the solitary, larger fish.  I personally like the blue and purple varieties that have fins similar to an angel fish.

The mollies love floating plants, live or fake.  They will pick at stuff trying to help you keep things clean (I did say try  ). 

The beta would love you rescuing it from a sad existence in such small confines.  A pointless piece of information about betas ...  they have a labyrinth breathing system to where they can go to the surface and breathe air directly ...  that is how that manage to survive in such horrid conditions.  They are very happy with 2-3 gallons, but those little cups, small bowls, and vases are torture.  If you have a snail problem, a beta will solve it!  They love devouring snails.

Good luck and I hope you find or someone suggests something that is right for you!!!
