I used plexi and silicone.... they can see each other. It should be fine.
A 26g is plenty for a small bp.... depending on how small you're talking; maybe too big.
I have mine currently in a 20g and he's a big boy.
And the large tanks are harder to heat. And the lamps kill humidity. When mine housed bps I had to spray it more frequently.... and kept the water under the lamp. But I had the lamp on a dimmer and also used a UTH so it didn't have to always burn as hard. I switched to smaller tanks because of the bulk of the 55g mainly... it was really in the way, very heavy and a little because of the extra maintanence.
It can be done... and can work just fine. Some people are just way too anal about things....
No offense to the anal![]()
