Predator fish for sale

[Taaron]

I have a 13" whitespotted bamboo shark for sale $150 OBO i will only let this shark go to a 180 gallon setup or more. Really cool shark though, eats almost anything that he can fit in his mouth.
Also have a panther grouper about 8 inches $50 obo
Also have a lunare wrasse 6 inches 50obo
A 7 inch engineer goby 20 obo

Please do your research on these fish as they will mostly likely only thrive in a fish only system that is about 120 gallon minimum for now excluding the engineer goby.
