Rose BTA Split last night

[Mageau11]

Hi everyone,

I'm new to the forum and new to the hobby.

I have a 9 month old 54 gallon Aqueon Corner Bowfront. It's not drilled, so I'm running the following on it:

-Fluval 406 Canister Filter (using Chemipure Elite, Seachem Matrix Carbon, SeaChem Purigen, and Seachem Phosguard as media within the filter in addition to the Fluval sponges and BioFoam)

- Aquamaxx HOB-1 Skimmer

-CPR Aquafuge 2 HOB Refugium (housing rubble rock, deep sand bed, and chaetomorpha macro algae)

-mp10wQD

-Gyre 230 (running in alternating Gyre mode)

-Apex 2016 controller system

-custom clear lid with mesh from Artfully Acrylic to keep my snowflake moray eel and melanarus wrasse from jumping.

I woke up this morning to see that my rose BTA had split in two. Both "pieces" seem happy and my True Percula has been bouncing back and forth between the two.

I've heard that stress can cause them to split, but can this also be a good thing too?

My water parameters for the most part have been in spec of late (battled some nitrates and phosphates that cause GHA, but everything is back in line and tank is looking much better) and the only major change has been that I just got the new mesh lid last week so I'm getting better light penetration from my T5's. Before I had the stock glass canopy that came with the tank that always had some condensation and salt creep on it, so I'm sure not as much light was getting through.

Anyone have some feedback on good and/or bad reasons/experiences with anemones splitting?

I don't know enough for any advice but I just wanted to let you know I love your
Ur tank

Sometimes they split for stress or water parameters being unstable.Other times they split naturally to reproduce

You read a lot about both stress splitting and happy splitting. My nems get about 10" and then split. They are beautiful, I have had them almost 1 year and not lost any. I don't worry about them splitting.

Given that they live so long they do not need to reproduce very often is the theory, so usually excessive splitting could be a sign it's needed conditions are not being met, but also a sudden change as in new tank is very common and almost expected unless your params were spot on similar to what it came from.
The only thing I see here is you are using a canister and media, sponge, and if you were to test your nitrates I'd guess they are higher than they could or should be, as sponge/media can be a nitrate sink, and nems do not like high nitrates, so if it were me, I'd at least remove that sponge.
Later you may want to think about swapping out that canister, but I will say your tank does look nice as is right now, but I'd watch nitrates as well as the usual stuff.
