I have had a 20 gallon tank for 4 1/2 and it is doing great! I have an angelfish, sunset gourami, platy, blood fin tetra, congo tetra, yo-yo loach, cat fish, and a super algee sucker (you are all gonna laugh at me...I can't remember what they are called) Anyway what else should I get? Whenever I get fish I usually just ask the pet store people and get what they say will work. But what do you all think? I want to get a dwarf gourami and two more tetras...the pink and blue ones...heehee I know I am terrible with what fish are called. :duh:
