So I made an impulse buy at fragtoberfest and bought a RBTA fairly small and I put him in my mixed reef with all acropora up top and sure enough he walked up to the top of my rocks the first night found a crevis stuck his foot in right in the middle of my 5 beautiful acropora mini colony’s. I can’t point a PH right at it cause I don’t wanna destroy my acro’s literally right next to it and I tried to ice cube in a bag but it’s foot is literally in a v shaped crevis at the top of my rock and it’s all epoxy together so I can’t remove the rock or chisel it, at this point I just wanna glue some rubble rock over it and see what happens. dang impulse buys! Sorry for the rant I’m just desperate and frustrated. I don’t wanna kill it but my acro’s are top priority.
