Group of 4 (maybe 5) young adult 'Black' or 'Black Pearl' calvus. Sizes 2"-4" or so. Showing signs of pairing. Likely one maybe two pairs. All 1-2 years old with the largest being the oldest and dominant fish. I've kept these in a 90 gallon mixed Tanganyikan community which has gotten a bit crowded with spawing competition, so giving this group up to make a little room. Very nice fish. The smallest 5th fish seems to have done the disappearing act - these fish are very good at squeezing into tight spots. If I can find it I will include it but for bidding purposes please assume only 4 in the group.
