from what I understand they slowly die in a closed system but there has been some success from what I've read you have to target feed them often with cyclopeeze and frozen oyster eggs but I did here alveopora is easier to keep
gonipora's are real nice I never had much luck with them though I even tried hydnipora. I have read that in capativity they seem to slowley die over time. Hopefuly you will have better luck with them.
Euphyllias,(torches, hammers, frogspawn); Acanthastrea (echinada, lorhowensis);Open Brains; Lobophyllias; Blastmussa; Candycane; Micromussa; Assorted Polyps; Gonioporas (red, blue or purple); some softies like Colts.
A lot of these Corals have "sweeper tentacles" that can STING other Corals, but they usually do OK with a little distance from each other.
As with anything, when something is dying or in decline, move it to a quarantine tank for special feeding or treatments. All corals will foul a tank when they decompose but I think that these on the list are fairly safe (not to have toxins).

Will lps work under a 36w pc in a 2.5 gallon pico if so what are some nice ones that aren't aggressive and when they die kill everything else or release toxin in the tank
