Hello, I have an 4 afrixalus sp.'s, and 1 ulgurensis (not sure on spelling). First off, what does the sp mean?? THen, how should I keep these guys when it comes to sunlight, temperature, humidity level, and water. Do they need a little pond in their enclosure, can they swim, and how hot is too dangerous? How cold is too cold?? I bought these cute little guys with no knowledge of this species, and have found it to be rather difficult to find any information about care of them. So, anything will help. Thanks
