So i am contemplating whether to keep or give away my bolivans in exchange for blue rams. I have a ph of 7.2 and im tyring to lower to about 7. Amonia 0, nitrite 0, nitrate 0. Temp is around 76-78. Fish i have currently are 5 corydoras, 1 angelfish, 2 sae, bn pleco, 3 red eye tetras( getting more), and the 2 bolivians. I just dont like the color of the bolivians, woud the blue rams be a good choice?
