I v been to fish town cheapest Fish in the tri boro, i guess, but water quality .....ify... Lots of tangs ( in a 20 gallon tank), angels, inverts, etc.
I bought live rock ( more like dead rock to me) about 1.5 years ago and had alot of trouble with it but as some seen managed. So i guess its not the product but also the care and the husbandry.
Best LFS....
