How many fish and corals in a 24 gal Nano?

Hi Paul

 

There are no hard and fast rules with regards to the number of corals you can keep in a volume of water although you need to take into account the corals environmental requirements and how quickly a coral may grow when placing them in the aquarium.

A very fast growing coral may quickly grow over other corals placed close by or the corals may 'fight' if they can reach each other with sweeper tentacles etc.

 

Light requirements will also play a part as if fast growing corals are placed high in the tank they may shadow out corals placed lower down and ultimately lead to their demise. Obviously don't pack corals in so tightly that they impede flow around the tank.

 

With four fish with maximum grow out length of 2-3" the nano would be close to fully stocked without compromising water quality and making the tank look too busy for a reef style set up.You may get away with a couple of small gobies for added interest as the smaller gobies dont add so much in the way of biological load.

 

Hope this helps, Regards Tony
