Yea Mine usually stay in the water by the filter. My one brown frog Fred likes to wedge himself between glass and under the filter. I tried putting gravel under the filter but he just digs it away and goes under it. Do you or anybody know why he does that? The temps at 68-71 at least that's what my temp sticker on the glass said on the land side. Also, I put mealworms in a dish and they haven't touch them and I put them in there around 12:00 EST. I don't know if its because they don't see into the dish and see the mealworms moving. Oh and mine stay hidden behind the fake plant when they are not in the water. I'm thinking about getting a bigger habitat for them and get a few more frogs too. Or Can I have 3 in a 10 gallon?
