Hi, I have been having troubles with my frogspawn. I was hoping to grow a big colony but the heads on some frags seem to be receeding. The tentacles barely extend and stay very short. However my hammer coral is doing very well and extends well too.
This is in my low tech nano tank. I am good about waterchanges and testing. Lately been looking close at Ca and Alk. (Tad low but not bad, did waterchanges.) But I am not sure if it is lighting, flow, picked at by shrimp, e.t.c. why is the frogspawn not happy but its brother, hammer, doing well? Thoughts???
Thanks,
Sam
