I was in AG this past weekend too. They said their pump just broke down for their saltwater selection so that might be why its a little run down looking at the moment. So I agree with the hit and miss thing.
You will have to teach me how to spot ich in tanks cus I never saw it in any store tank before even though it was probably right in front of my eyes.
I did however buy two discus from Ocean Odysee before and a few plants and by the end of the week all my fish had ich and almost lost the whole group back in April 2012! Since then I haven't spent a penny there because the store in general just is very dirty IMO.
Last Thursday I ventured up to bay city and went into Saldons or something. They had all kinds of great looking fish. Hard not to add to my tank. I also saw a wings and things but showed up 30 minutes too late. Found out they close at 6...
Mr. Fish in Bay city is also someones home. Not too sure who said that was a fish store but they were wrong!
You also missed Petsmart on Titty wassy. I buy my frozen food from there and wonder their store for odds and ends.
