Thanks for the suggestions and ideas. I'm sure it's going to be hard or nearly impossible, but I will still try to figure something out. I like the island idea a lot, but it still leaves the possibility of the glass and of course swimming. The glass seems to be the hardest part of the whole thing. I had tincs that were on the glass almost all day!

On a side note, besides putting more terrirtorial species with shy guys, is the only negative problem them breeding together? I could stick with same sex frogs if that's the only other concern. What about tincs and azeureus? Or tincs and leucs (that's what I was looking at for a combination as far as a stark contrast in colors)? Compatable?
