hahaha . yes there is a fish tank in the back but the things you can see above it are lights. in one of the pics you can see description. they are descriptions of the names of the fish my friend has in his pond. and a chart to show when the fish last ate and what they ate. he keeps local see fish like dog fish bream and conger eels.. im just lucky to know someone who has the room and the same pasion for fish as i have.
