I know what your saying about pets at home, mine is usually really bad too, always at least one fish in the tank looks unwell.
i have to admit i got 10 neon tetras and 4 ottos from pets at home and some bogwood, live plants and sand instead of gravel and so far (touch wood) i am really pleased. my tank looks the best its ever been by far and the only fault i can say with the fish is that 1. the neon tetras were mixed with some cardinal tetras and ended up with two cardinals, which i dont mind as it gives a bit more colour to the shoal. 2. the only problem with one of them is it has black markings on him, one of the cardinals, they gave me 2 cardinals 8 neons. which i still dont know what it is, im hoping he may have just been born like it, as he is swimming healthily with the shoal ect. just his apperence seems to be the problem?
3. which i love them for doing, is they give me a baby neon tetra that is just big enough for no one to eat and hes soooo cute! i love him
But the only reason why i got them from pets at home is my normal lfs i usually go to wasnt going to get neons or ottos in till tuesday, and i needed to get them in yesterday. My pets at home had just moved to the other end of the retail park and so had got new stock in and new tanks. i checked the tanks through and i must admit for pets at home they where pretty spotless!
iv give them this chance, if anything goes rong then yes, never again, but if it goes mainly ok and next time i have a look and the fish look ok, then my pets at home may become my local LFS. who knows?
i hope you do report your pets at home as it may make a difference and i dont half feel sorry for some fish in really horrible condiotions.
My first LFS i ever went to was petstar i think its name was, something along those lines, and the tanks where distcusting! there was one with male guppys in AND females! and they where always breeding! there where guppys that where still alive trying to swim away from guppys eating them but she had no back fin to swim with, this was when we went back to get some more, i was about 15 at the time and i nearly broke out into tears!
some of the tanks you could just see shadows of fish through all the algae!

i have never seen such a mess before in my life, i was going to report it,but my friends mum was talking about it and she had reported it and her friend has aswell so...
i havent been in there since, however i hope there is a very big change.
thanks x
