What’s wrong with anemone

[iratoha]

Good day. We are new in this hobby and recently went through big tragedy, where all our fish and even one shrimp died. Probably because of velvet or maybe we overdosed them during treatment. Anyway when all this happened our anemone seemed pretty good, it bloomed every day. But last couple days it looks like this. We have 50 gallons tank, with such pump on top. Now we trying to make water good again, because after tragedy all parameters were very high. We made almost 60% water change, also we put this according to instructions. So now parameters are this
KH 196.9 ppm (we were told this parameter does matter only for reef tanks but just in case)
Calcium 440 ppm
Phosphate 0.25
Ammonia 0.25
Nitrate 20 I don’t know how to lower it, if even such big water change didn’t help.
There is no fish now, only 3 crabs, snails, slugs, centipedes (long pink creatures with multiple legs) but I put little bit of food in tank so they will have something to eat. Thank you.

Anemones in general don’t do well in new tanks. They will be okay for a while and then just slowly die. I don’t have specific advice though.

Looks like it is in process of splitting ?

I hoped so. But That crack disappeared now, so I don’t think so.

anemones would be part of reef tanks although kh isnt as important they still like it stable
are you using tap water? saw the seachem prime. this might be one of the issues if you are

Sorry, your reply doesn’t look finished. Yes, we added Prime. We used water from fish store, ready to use for water exchange.

Ok, now this happening. I don’t know, is it poop?

Agreed, defiantly looks like its splitting to me. And I bet its due to all the changes in the tank from stress.

edit, new photos don't look good now. May have stopped splitting.
