Hi, im pretty new to salwater reef aquariums to start. my question is about my sebae anemone. its mouth seems to be open more in the last week more so than in the last month. the mouth is dialated to about the sice of a number two pencile give or take. ive herd that this is not a good sign. i have an anemone crab living with it right now also.. it is very white with blue tips and all his fingers seem to be intact. he has seated in the tank fine from the get go but i havent seen him eat much... as for my tank, all is running very well and i have had no problems with anything thus far. i have had the tank running for aprox 2-3 months and i bought it from someone that had glass anemone invasion that had it running for aprox three years. i did most all the right stuff to rid them and have not seen them since... any way i guess any info would help. please and thank you.. b-o-b-s.
