I had one that split and then a couple of weeks later the original just shriveled up in the rock and never came out again. It didn't cause any water parameter problems - it just shriveled up and went away.
I had a BTA disapear about 2 months ago and never seen it since, never had any water problems... I think he went suicidal... he was very healthy too... wierd
Is it a captive raised or wild caught? I had 3 wild caught that never adapted to my tank. The first captive raised I got is now 9 anenomes (in our tanks) and many splitts have been given away.
Nope, still MIA. I did check for ammonia,trites and trates yesterday just incase. I am doing a water change later today and will test again just incase he bites the dust.
I once had a Rose that split twice. One ended up in the overflow, and the other 2 just kinda disappeared. In a tank that big, you may never find them not any traces of them.
