By the way it’s reaching, I’m guessing it wasn’t getting enough light.We got an RBTA after we already had our clowns in the tank for over 6 months. The clowns wanted nothing to do with the RBTA. The RBTA died within two months of owning it, never moved from its spot (we bought it on the rock it had been on at the lfs) we had three different sources tell us water params we’re fine (some on this site, too) he ate fine for the first month (fed him pieces of fresh scallop from a local fish market) but eventually ended up loosing all zoo, then lost all its tentacles and the disk just disintegrated. We pulled it out of the tank just after the expulsion of the zoo, because I guess RTBA are toxic when they die? Maybe my clowns never took to it because they knew it was sick? Photos inserted from day of arrival up to when it started dying.
