It's a 48x12, 55 gallon tank. It has two male Dragon's Blood (were supposed to be a pair), a female jacobfreibergi (the male died), a pair of red shoulder peacocks, a pair of hap flamebacks, 3 hap ahli and a rainbow shark. We've had the rainbow shark for 3 years so we're trying not to get rid of him, but he seems to terrorize some of the other fish
