Hi All. Totally new to this game & just got ourselves a 42 gallon tank with 6 cichlids. (3 Labidchromis & 3 Blue Acara) Only had them a week & had to change one Blue as it became extremely aggressive to a femaile. That female has since been hiding in a small cave & only comes out to eat, tho only eats very little. Is she pregnant & what should I do? Appreciate any guidance guy's.
