I was wondering if anyone has any experience with Ruby Cardinals.
I purchased a single 3 weeks ago and ordered 2 more since they're a schooling fish. And have had the other 2 for 2 weeks. And I haven't seen them since. I was wondering if they are this shy always. They are in a 114 gallon tank with 4 tiger tail seahorses, a Citron goby, and a Bengai cardinal. So a calm and peaceful tank. Thanks in advance
