The pool is rated 500 gallons, however the volume of water currently in it is 400 gallon. I haven't fully filled the pond yet since there is some work going on with it. Once its done, it shall be filled completely.
Another update: All the fish have been doing great. Since I removed the snakehead, I have added my silver arowana in the pond and a little surprise aswell, in which
Cichlids-r-beasts will be particularly interested it.
