So I'm setting up a 30 gallon hill stream tank with about a 900 gallon per hour flow rate. Most of the flow will be aimed at the bottom of the tank. I'm planning to get all your regular bottom dwelling hill stream species, but I'm in need of some fish for the midwater. Im tempted by Odessa barbs...

I just bought two cpo crays for my nano tank, I have one male and one female. The tank size is 10g and I’ve read on here that they need hiding spots. I have tons of spots for them to hide such as kola logs, live plants, pots, and morimo balls. My problem is that I only see one, will they hide a lot?
