They are super energetic and always cleaning the tank. I'm getting a pair of blue rams so I'm trying to think of what to add to the bottom of my tank. I like yo yo loaches and Panda Cory's. but I don't want to disturb the rams. As for mid to high I'm going cardinal rams, rummynose tetras and possibly harlequin rasboras or ill stick with the 7 black skirts. I've just had bad experiences with the skirts in a community tank.
