Hi,
I bought a bubble tip last week.....I fed it a small silverside day before yesterday. Today I woke up and it looks shriveled up. I thought it was dead and went to remove it from the
live rock. It is attached and moved its foot so I left it alone. I read they may do this when they are getting rid of waste.
Guess my question is how can I tell if it is dying

??
I have a 47 gal bow with a marineland 220 cannister filter. I run a
skimmer and have the
powerhead at the top of the tank for surface water movement. The lighting is a current T5 4x39. My S.G. was 1.024 this a.m.
ammonia,
nitrite were 0. I had a small amt of
nitrate so I did about a 5 gal.
water change
Thanks for any advice,
