I have began stocking my 55g planted tank. So far, I have 9 Cherry Barbs and 3 Otos in the tank. The next group I plan to add is the cories. I want to try to find 5 Leopards, but may have to go with something easier to find locally.
I know they are nocturnal and need some place to "hide out" during the day. How much room would 5 need and how dark should it be. I have slate set up in my tank now that "might" be considered a cave, but is more like a bridge, IMO (see image). The tunnel/cave/opening is about 6 or 7 inches from front to back. It's not very "private" and the barbs tend to swim through it regularly.
Is my slate sufficient? If not, I am interested in what others have done by means of DIY that appears somewhat natural (would love to see images).
Thanks in advance!
