[winston]

hey my puffer just died recently and im going to get some other fish. i have a 20 gallon with a couple ghost shrimp and a red tail shark. i am planning on geting 2 clown loaches and a ancistrus cat fish. how much room do i have still? to get more fish?

you should keep in mind that clown loaches are schooling fish that get up to 12inches long, and do best in schools of at least 3. Red tails also require a lot of swiming room.

red tails also becoem aggressive and territorial when they get older
