Looking for some advice what I could do/add to get my new batch of 7x 3-3.5" cichla kelberi to stop hiding. Got them about a several days ago and for the majority of the time they are huddled together behind the filter intake. I tried adding a small goldfish and Bparrot to help them out/show them how to eat but only one or two of them venture out for food. Thanks in advance for any input/advice
