Here are some of mine. The first is one we aren't sure of the genus even, probably a Tomiyamichthys sp. we've had it 15 months and we just call it the freaky goby. It pairs with peppermint pistols. The second is a yellow watchman we've had about a year now. The third is our yasha we have had over a year. The 4th is the y-bar goby Cryptocentrus fasciatus. The 5th is our circus goby. All of these are long term captives.
