Do Diamond Gobies Eat Their Own Poop?

[huckjai]

I currently have a diamond goby and a red firefish in a QT tank. These two are eating machines. They eat a lore more food than other fish I have in QT. I normally siphon up left over food and waste twice a day, but the goby and firefish tank is always clean.

My goby eats everything he can find on the sandbed, including his own ****. you should be happy it is doing such a good job cleaning the tank! Enjoy
