thinking from a bio point of view , theoretically , if the oxygen produced is enough to sustain the coral from an indirect lightsource (taking into account this is probably a metal mushroom of some sort which dosent die under heat), yeah why not?
lol joking la cannot one la , dude , 1 the algae sure grow until you bin che che , 2 theres no metal mushroom , 3 the mushroom coral needs like alot and i mean ALOT of zooxanthellae bact to produce enough oxygen for itself and the bacteria. lol the bacteria also need oxygen right.
tho , i aplaud the idea , lol imagine if it were feasible , sure got new fad in town , coral in a bottle (oh man that rhymes )
