I totally understand that feeling. Its like they know, so they do that on purpose.I've got 1 mature head (original), 4 teens, 2 babies all open heads. Something will happen to make tank or even the frag. Every time I grow any paly or zoa that I care about and it gets past 10 heads something happens such as melting etc... The items I don't care about or don't pay as much attention to flourish LOL. Good luck everyone
I have a single Kessil aw 360. they do not get a ton of light where they are at but enough. I will add them to my other radio light tank. Possibly bad idea but I spend more time on that tankMaybe slowed too because of lighting? They seem to be stretching pretty hard, any chance you have T5's at the end of their life? Maybe move them up a little?
