I like using the following for my tanks: Clown loaches, small male cichlids, plecos, and synodontis eruptus.
jgentry;2738137; said:How big is your tank? Severums and chocolates are not very aggessive so you could do any of the larger tetras. I personally am not a silver dollar fan. They get big and tend to be very spastic. I like the clown loach idea best. They are very active and colorful.
Mable hatchets
Blackskirt tetras
Clown loaches
Yo-yo Loaches
Congo Tetras
Rainbows
These would be my first choices for a planted tank. I think 4-6 clown or yo-yo loaches and 6-10 congo tetras would look great with chocolates and severums.
