My frogspawn is starting to receed in some places and I don't understand why. Thy parameters are fine I did have a slightly elevated ammonia level I think because of a keyna frag that floated away and I couldn't find it any where that probably died and caused the slight spike. I did 2 good size h20 changes and everything is back to normal but the frogspan still doesn't look great. I use to spot feed them but the did all right without me doing that so I stoped but I started again. Any sugesstions I can get more into the specifics with some questions but don't want to make this too long. Thanks for the input. Mike
