Google a bubble tip anem. And if it was white, then it means it was unhealthy. They shouldn't be white (It looks darker now? which looks to be a good sign [I think!]). Just going off what I've heard other people talk about nems. Best of luck :)
Jump for a BTA....doesn't have to be a Lamborghini LE Ultra Space Anemone from planet Venus or something but even a GBTA or a RGBT would be a fun one to have....the Clowns would love that....
This is the LTA I had in my 150g and it was about a foot across with a lot of reach. They get even bigger. They are an amazing anemone but be ready to give up a lot of space if you attempt to house one. Good luck!
