I'm not trying to be a jerk, but I read your opening post and was a little angry at what I read. Please correct if I am wrong but you lost power while out over the weekend and the tank took a bad turn and never fully recovered? You only feed your fish once a month?
You should not be allowed to set this tank up because from what I am reading you refused to take care of your responsibility as a pet owner once things kinda went wrong? Feed the Dottyback once a month, thats pretty bad and rather upsetting.
Also you need to prepare better for your pets with a back up plan or someone to watch your tank while your away. Its not fair to the animals to leave them on there own with no support.
I have not read through this whole thread because I am a flat out disgusted.
