My mushroom has been doing great lately. Every day is out a 3 to 4 inches in diameter. Today it's about 1 or so. It's not spread out like it usually is. Is this something to be concerned with?
I checked:
Ammonia: 0
Nitrite: 0
Nitrate: <12.5
Cal: 400 to 440
if the colors is fading or it looks like he's trying to barf something stringy yeah you should be concerned;
give him a couple of days and check it some other invert is bothering him
you could always feed it.......maybe it is hungry.....seriously though do you feed it? I feed mine about once a month a small piece of silversides when I feed the anemone....it hasn't really grown much but then I have it isolated so it can't really spread to anything......it's about 3inches across when inflated....
Actually, I haven't feed frozen mysis since I got ich. Whoops.... I also lost my emerald crab today maybe this could be it as well? I was giving him sea veggies every few days.
