Hi. Today I decided to add copepods into my tank and the instruction said wait for 30 minutes before turning the pumps and everything back on. Then I lost track of time and 30 minutes turned into an hour. The water is completely still and when I turn the light back on the tomini tang in there is not moving at all and the eibli angel hiding in rock. Tank is 65g and only two fish in there. I'm probably overreacting but just want to make sure it won't make the fish sick as they're not dead now lol. Thanks in advance for any input!
