Thank you for the informative and prompt reply. I have water dechlorinator, a spray bottle, calcium powder, and lights for both tanks (timer's coming soon). there was only one light for as long as i can remember, and he would light each tank every other day. I went and got another light after reading about the importance of keeping a 12hr cycle. Its a 25uvb fluorescent tube. Is it ok to have the different species in the same tank? I definitely observed some aggressive/territorial behavior during feeding. Also, how often should I change the water?
