We moved our 3 Cichlids from a 20 gallon tank to a 47 gallon tank with more decorations and places to hide* about a week ago. Ever since, they will not come to the top for food. They also hide all day and never come out and swim around. At least one has red gills but I have tested the water for PH level and ammonia/nitrates and everything seems fine. It's at the same temp the old tank was, so I don't know whats wrong.
Correction: 37 Gallon tank
