If I were you I would get pygmy Corydoras. (If it is possible that is.)
Thanks so much! I think that i will be getting the pygmy cories, and have them special order/requested from Petsmart. i was reading on their site, and turns out, they probably breed them in-store, so they are already in my water conditions :) How many would you recommend?
Will the gravel bother them?
Also, one last question,
how should i put them in without stressing my betta who has been in the tank for almost 2 years?>
