Who Gives A Fish Forums

Certain fish need specific amounts of water, like neptunes that require at least 1 U.S. gallon per fish. You should research the type of fish you're looking to get or already have, and see what the stocking recommendations are. =)

I've got two types of frogspawn coral going on - one's purple, the other's green-tipped. Every day around 8 pm, the purple one shrinks up and the green one pretty much disappears into its skeleton. They're out for an hour, then they're back to normal. Lights are still on, no changes there - 11 hours ...

Mine did the same thing, around 7-8pm for a bit, now it's happy and stays open till the lights dim.
