I've run out of water tests ,, I have a seachem ammonia tester ,, which is showing fine ,, there is an angel fish , 2 giant danios and a plec ,, I do hoover the gravel and clean tank every week ,, do u think I could be hoovering them away ,, am I cleaning tank to often ,, she changes color alot from very pale to almost black ,, really annoying ,, was hoping for fry a few month back ,, ready to give up hope ,, I reckon they are defo a couple ,, he does chase her round now and again ,, nothing major although she does make a racket bumping into things and jumping in and out of water when it starts lol
