Quick question for those with imitators. My pair, particularly the female, likes to sleep as high as possible. She attempts to squeeze herself into the upper track of the door each night, though unfortunately cannot fit. My begonia is getting quite tall, but doesn't reach the top yet, nor does the fittonia.
Is there another plant that they would prefer or something that should be added to the tank that is more appropriate for sleeping? It's possible it really doesn't matter, but the behavior is consistent, so i figure I should ask.
