Hello!
Can anyone tell me at what point in development I should provide a land surface for my developing bullfrog tadpoles? Right now they are in an aquarium which has no land surface but has a small surface they could climb partway on if they needed to... I can't drain the tank down to provide land surface as it's a hex tank (not a lot of surface space) and the filter wouldn't work if I lowered the water level...
I will have to switch them to a small tank with no filtration until I get the supplies I ordered to fix my 10 gallon aquarium so I want to keep them in the tank they're in as long as possible, but don't want to accidentally drown them when they develop lungs!
Thanks!
