I too have had nothing but good experiences with Exotic Aquatic in Broward. Here is why I support this particular LFS:
1) the staff is well informed;
2) they are honest about what will and won't be compatible with your current tank mates;
3) they will never sell you a fish that looks ill and will tell you if a fish is not eating;
4)unlike some larger nearby chain stores, this shop cares about its livestock, and will actually treat fish that become ill rather than just ignoring them.
