True for the most part. I think alot of that has to do with whether or not you leave the fry with the parents . Leaving them in there will have the parents guarding them for longer and as the fry move around they will come into conflict with the other pairs territory. Removing them once they are free swimming helps to eleminate alot of that. I suppose it comes down to how you manage things. I've done multiple pairs in a 55g without problems , but I removed the fry. If one doesn't intending on breeding them , then one pair and let nature take its course. Not trying to argue with you CL , just my 2 cents . :wink:2 pairs is asking A LOT for a 55 gal.
I know your not! Seriously it all goes by opinions and experience. Just because you don't agree with it doesn't mean your trying to argue and it usually won't lead to arguing! If someone doesn't agree with me it's cool! I won't try and argue because its your opinion! I believe it could work and I could see it work if you remove the fry quickly and make the pairs have breeding spots on opposite sides of the tank and not have them spawn in the center by leaving an open space. And I will admit I do not have any experience with 2 pairs in one tank. I just don't won't to try and attempt it unless it's big enough like a 75 gal or a 125 gal. I am just happy with one pair in a tank and the cichlids like it as well! I am just going by what will make the cichlids happy and which in turn will make me happy! I have just found that sticking with one pair in one tank is AWESOME enough and the best for me! Also I am going through experience with my Sajica and through them I have found to just have one pair per tank and don't add any tankmates!Not trying to argue with you CL , just my 2 cents .
