Has anyone ever kept fully aquatic amphibians (like African clawed frogs or axolotls) in a riparium? I thought it might be a way to have a planted tank with these critters that probably would tear up many aquatic plants...
Or are they too sensitive to fertilizers, etc in the water?
I have a planted tank with african clawed frogs, three large females. They don't really wreck it that badly but kicked up plants can happen, they also have a habit of biting plants during feeding time because they mistake it for food, so they are prone to biting leaves off.
Overall, it's not too bad. They will probably stream roll over delicate plants though.
They would do fine in a riparium but just keep a few things in mind.
If you have no top, they will try to escape. If you keep the water level low enough and don't give them a way to climb out you should be okay.
If you want other inhabitants in your riparium (like fish), african clawed frogs will most likely eat them. If you have any terrestrial inhabitants, they will be hunted and consumed if they are small enough to fit in the frogs mouth.
They prefer cool water 68F-72F, long term exposure to higher temperatures can lead to health issues. Axolotls need even lower temperatures, they are a cold water species.
These frogs like to bask and preferred subdued lighting, so don't blast them with high powered lights. Strong lights can also blind them.
