RBTA on the move

[seanm001]

After three months in the same front & center spot in my tank, my RBTA decided to find a better place to call home. After roaming around for a day, he seems to have settled down in the top corner between the glass and the return plumbing outlet.

The weird thing is, it's likely the darkest part of the tank and he's hanging from the wall such that the return flow is going across his face and the overflow is going over his foot. I thought RBTAs like moderate to high light and moderate flow?

I tried turning off all the flow in the tank and trying to get him to settle in a seemingly more suitable spot and I also tried getting him to settle on a piece of rock in the quarantine tank and then placing the rock somewhere in the tank, but it just picks up and wanders.

Does this sound like behavior that I should be concerned about? I don't really mind it staying there as it's well away from the corals and opened up a huge amount of rock space for more corals, but I don't want to ignore it if it's symptomatic of a problem.

All parameters test out well (zero ammonia & nitrite, nitrate 5 ppm or less, zero phosphate, stable pH of 8.4 and salinity at 34 ppt). I target feed it two to three times a week half a dinner shrimp and it usually manages to pull random pieces of mysis, brine, or NLS pellets from the water column also.

Thanks,
Sean

Just make sure your intakes are covered. It is unlikely it will stay permanently in the place you described.

hmm... if it seems happy there, then I guess that is where it is going to stay. I have tried moving mine where I wanted it to be and every time I do that, it will move and put itself where it wants to be. I know that they have a simply CNS, but it seems that somewhere in that bundle of neuronal fibers that they call a brain lies the ability to know where it wants to call home and it will have the last say lol.
