Hello! New member here with a stocking question- We have a 65 gallon with two yellow labs, one red zebra, four Pseudotropheus acei, and one blue Pseudotropheus socolofi. We have had a peacock tank with yellow labs and blue acei in the past. We would like to add in a couple more fish to this tank, and would love suggestions regarding what other species we can add in to this mix. Our canister filter does 264 gph (1000L/hr) and we perform water changes twice weekly. Thank you!
