I just received 8 CPDs yesterday and put them in my Quarantine tank with med trio. I just have a few clippings from a plant, small rock, heater, and sponge filter. It is bare bottom other than what I listed. The fish are very skittish and frantically swimming around when I observe the tank. I feel they might be stressing themselves out to much. Tank parameters are well within normal ranges.
Is this normal behavior for these fish?
Should add more structure in my quarantine tank?
