i need to know how long a pictus cat fish grows and how many gallons one needs and if there's any other fish i could put in a 10 gallon tank.:headbang2:
Guppies and mollies are good schooling fish for a ten gallon; some tetras will also do well in a ten. If you want a specimen fish, a betta or one of the smaller gouramis is good. Also consider shrimp and mystery snails.
*EDIT* Sorry, I was typing at the same time as JPappy. Good suggestions, but I don't think otos are a good choice for a novice fishkeeper.
