my goldfish Billy has been darting around his tank randomly and sometimes right after he gets so calm you'd think he was dead. is there a reson he would have this behaior?
how long has the tank been set up?
Its cause of some virul infection probablly.
about four years, he was the first in his tank along with two other fish that dued a short while ago
What are your exact reaadings for ammonia, nitrite, & nitrate? How often & how big (%) are your water changes? I suspect its an issue with water quality.
i am hopefully going to get the water cheacked soon (i was going to get it cheacked today but forgot) i change the water25-50 % every two weeks
Please do a 50% water change with temperature matched, properly conditioned water as soon as possible & continue to do this atleast once a week (2x would be better). Please get your water tested asap- make sure you ask specifically for your exact readings for ammonia, nitrite, nitrate & ph & write them down. Its 'ok' or its 'safe' is not sufficient. Please post these results here when you are able to. We need to address any water quality issues before considering if something else may be amiss.
@ ricky: six years becuase it housed other fish before billy came into it
