When you say "good quality water" - this doesn't tell us anything.
What are the actual numerical readings for Ammonia, nitrite and nitrate?
20 gallon tank - tall or long?
What else do you have in the tank? Species and number per please
How long has the tank been set up?
Was your tank cycled?
Do you feed anything other than bloodworms? Bloodworms should not be the staple of the frogs diet
How long have you had the frog?
Have you seen it shed recently?
You often won't see it poo - so don't be concerned about that.
Can you describe your tank set up - substrate, decor....pictures of the tank and frog would be immensely helpful.
Iv had the tank for a month its a long tank and I dont know the levels of nitrite. There is a moss ball and another plant along with two fake plants and decoration. I think I have seen it shed, there was stuff coming off the frog about a week ago. I have two bottom feeders two suckers two rosy daniels two mollys and three red tailed fish dont knwo the actual name of them. I feed bloodworms and tropical crisps. I just would like to know if it is different for the frogs to float on the surface alot?
They are not sharks all my fish are tropical community, they are yellow and black. But is it normal for the frogs to stay at the surface for long periods at a time or is there definatly a problem? Il get back with the results.
