Hi. I have a dilemma and I need advice. I have 2 x75 gallons tanks. In 1.tank: one pair polleni cichlids (male is very agressive, beat your female and other fish too), pair JD, pair blue eyes cichlids and one Oscar . In 2. tank: pair of pollenI cichlids (male is relative peacefull), several young blue eyes cichlids and convict cichlids. I have the idea into one tank two pairs of polleni and other cichlids to second aquarium. It's a good idea, or is the problem? Polleni are three year old. Thank you for every idea.
