Of all species, I have never seen as much contradiction as this one. I have been reading everything I can about pygmies and finally got 1. nobody seems to agree on substrate. right now I have coconut about 2". lighting nobody agrees on this, I have repti 2.0 florescent. heat no one agrees, Right now I have none just room temp about 70 day and 67 night. The guy I bought them from says if they need any extra heat they will climb to the flourescent light for a little warmth, any other is too much. humidity I mist twice a day about the only thing that is agreed upon although I found a contradiction. I have 10 gallon glass aqaurium w/ screen top, with live plants and branches. I would love to set up a 55 gal. aquar. I have for display and breeding group, but want to know what the consensus is on these topics. I have other questions, but just wonder what works best for everyone. Any help would be appreciated. I think I am going to purchase some more from flchams.com. He has a few gravids. I dont want to take up all his time with a ton of questions.
