New to pikes not new to fish. I'm currently planning a SA cichlid tank in a 135 gallon tank. I plan on stocking it with a single severum, a group of guianacara, BN pleco, and potentially a pair of aequidens of some sort. I was considering a pair or so of pike cichlids (or potentially just a single). I've researched the regani pike but my water is a bit on the hard side with a pH of 7.8. I've seen the compressiceps pike suggested as a better match but wanted to know if there were any other options that would not eat or beat up on the other fish?
