Hey guys just got a pair of these fish, which i presume are male and female from a large bump on the head of the male, much like a cichlid. The store says they are gobies, but i'm not really sure what species they are. Can anyone help me find the species of this fish? They swim very slowly and often stay still in one place for some time, they like hiding under rocks. The head of the male has a bump much like a bumphead cichlid. Both the male and female are very colorful with reddish fins and various colors on their brown mottled body. Any ideas???
