I have a 20 gallon long that my whites is in . But I didn't think that would be good for my RETF because it isn't a tall. I thought about getting a second whites. Would the 20 be good enough for that? I had a hard time finding my one RETF so I figure I wont get another for awhile. Thanks for yall's help. So is it normal for him to be a froggy vampire and sleep so much? He actually opened his eyes this morning and looked at me then went right back to sleep.
