Stopping rbta to grow upward.

[foxngn]

Hi guys, i had this rbta for 5 months, it's been split like 3 months back.

The splitted version of rbta was doing well eversince. It never had a need to reach for light, i also did fed it occasionally.
But yesterday it started to act weird and pull itself up.

Is there anyway i could stop it from growing towards up?

Here i attached the before and after pictures.

Just reaching for more light and/or flow. Totally normal. You could try moving it up a bit but if its happy, I'd let it be.

I think my flow is quite alright, enough for it to be waving.
Actually my main concerns is afraid it will touch the monti or those euphyllia on top of it.

I could ramp up my light, as currently it's runs abt 80% peak.
