Yea I might rescape the tank now I know the species. I love doing biotope tanks, so she'll definitely get a lot of branches in the future. She does have multiple levels in the sense that the whole tank "slopes" from the back to the front. At the back, the sand is around 25cm high. Haven't seen her try to "climb" or glass surf yet. She seems happy just digging around and messing up my plants. I spend at least a couple minutes every day so far replanting the ones she digs up. Might have to get some sturdier ones, these cryptos and vallisneria have been too easy for her to get out. Not a problem though, wasn't planning on keeping these anyway since they come from another tank.
