Appreciate the responses. I am going to start doing the no food thing a couple days out of the week right away...actually today since I am leaving town. These guys eat me out of house and home anyway, helping the budget out sounds great! I have them in 2 separate tanks but was concerned with the larger tank because it is a community tank, don't want them to go crazy on each other. One last questions, lights in the tank on or off? They are in a room that gets pretty good sunlight. Just keep the lights off? The smaller tank in my bedroom gets no light, so I am imagining to just keep those on the entire time. Does this all sound right? Thanks guys.
