Bta unhappy

[Matt Miller]

My tank is going on 2 years old, anemone been fine for months.

I did a wc and salinity went up to about 1.029, normally I keep at 1.027. it stayed high for about a week when I caught it and started bringing it down.

I checked because my bta had started cruising all around the tank, it's been in the same spot since I put it in the tank months ago.

I'm wondering if my light is going bad already, it's less than 2 years old and running saxby preset. Now it hangs out near the top of my rocks and hides overnight.

I have a WB 60.2 with aiprime hd 16, only 2 clowns and 1 6-line. No skimmer, fuge with red ogo and chaeto. 0 phos, 0 nitrates.

It's been on the move about 2-3 weeks now, and seems slightly smaller than before.

Should I just keep watching for more signs of trouble? Tia

Many times they’re sensitive to the slightest change in flow and lighting and will wind up right back where they started. I wouldn’t worry about lighting unless it starts bleaching or hangs out at the top of the tank.

Your increase in salinity probably also caused a big fluctuation in ALK as well as it is a portion of what makes water salty. BTAs do not like Alkalinity changes. That is probably what triggered it moving around.
BTAs require some phosphates to live and love nitrates as they are a food source for them. Your low or non existent levels are probably why it is declining in size and health.
