William Rogers Awesome fish store. Got a few vampire shrimp and some plants, they look great. The dude there who’s the owner is super nice and they have awesome prices on their plants too so 10/10.
CTay2357 Great local shop for fish. The owner knows his stuff and was friendly and accommodating to our questions and needs. We'll definitely be back!
david ice A newer store in the St. Louis area locally owned and operated I got to talk with Caleb and he was really open and honest also allowed me to see what other fish options he could bring in that maybe weren’t seen this store has lots of potential can’t wait to see how it evolves
