Hi everyone. I am new to the website. I have had African Cichlids and had problems with aggression but I had a 25 gallon tank. We went to a restaurant and my daughter (16 months) saw the fish and loves them. I was thinking about starting this again. I have since sold my tank so I will need a new one. I am interested in a 45 or 50 gallon hex. What do you guys suggest? How many fish can I have? Is a tank and filter at Pet Smart any good? I want to keep them from eatting each others fins, that was the problem I had last time. Everyday I woke up my Cichlids were beat up.
