Hello all, I have a 75 gallon Tank that is currently stocked with 30 Demasoni juvies. They are in the 1.25 to 1.5 inch range. I have read they will reach around 3 inches when grown. I have plenty of rock structure in the tank and so far not to much aggression. They have been living together now for about 1 month. The tank is well cycled with good water quality. I was thinking about adding 8-10 yellow labs about the same size to the tank. I have read that these two get along fairly well and I'm not really expecting any aggresion issues. The tank is filtered with two (2) Eheim classic 2215's. I do weekly 25% water changes religously. My question is.... Will this be too much once these fish reach adulthood?
