They seem to really enjoy it and enjoy swimming and ''walking'' all around. If they want to go under a leaf or something that is close to the ground it's no trouble for them to maneuver in without any worry. A while ago I switched all my tanks over to different sands (had gravel previously). Been extremely happy with it. I need to keep taking photos and work on getting some clearer ones if I can keep using my bros camera. One of the frogs has taken to crawling all over my largest marimo ball and laying on it, too cute! I have all live plants too, they seem to enjoy them as well.
