The place that I found is off Westheimer here in Houston. It's called Fishland. The place is sometimes hit and miss since they do have MANY big pieces for like $30 but most of the time I go in an spend $20-30 in just frags
and get quite a few. They always sell all loose shrooms
for $1 and loose zoos for $2. Most of the time I can even get small nice corals for $5-10 and they usually never have anything over like around $30 and those are REALLY nice pieces.
