On 2/17/25 I visited. I started up a reef aquarium and wanted to check out their saltwater offerings. I've never seen anything more disgusting. Most of the tanks were empty of life with many having a cyanobacteria (fuzzy dark maroon stuff) outbreak. They are a freshwater fish store, not a marine fish store.

I came across this store as I wanted a starter fish tank set. The prices here are marked way up. I saw the same tank across the street at Petco for half the price. They do have a good variety of fish and the staff was very friendly. I just wish they would give honest prices.

Nice fish options and staff are nice. But way too over priced! Saw so many dead fish for a private owned fish store, they need to be better taken care of. I see less dead fish at my local PetSmart. Rip off store in my opinion! Heaters,filters and other small stuff too much wish I was rich Please be fair and honest with prices Java moss all look dead waste of gas money
