This is my 1st one and it is small, about 2 inches across. It was sold to me as an LTA, yet Tentacles don't seem as long as pics I see. I've had it for 2 weeks. Some times it looks great, other times it seems to swallow itself, right now the mouth is HUGE and the tentacls are tiny!
It's in a 33gal tank (same foot print as a 55, but shorter) and has 130 watts of PC. I don't think that light is the problem. Everything I test: PH, ALk, Calcium, temp, iodine, Amonium, Nitrate, Nitrite... all are right on. However, I did learn to add PH up VERY slowly.
I have 2 pepermint shirmp (Lysmata wurdemanni) that have been picking at it... clearly not appreciated. I had assumed that they would get stung sooner or later and learn a lesson, but that seems not to be the case. Should I get them out?
I've tried feeding it a little, brine and phytoplankton... can't tell if it is really eating anything. Should I give it something more significant? Gammarus, Krill, pellets? The pepermints? (kidding)
To round out my frustration the TR A. Ocellaris loved the thing on the 1st day and hasn't been back.
Thanks VERY much for ANY help or suggestions.
