[Delphinus]

Can't really add more advice here, but .. I do have some bad news for you. Yellow tells me two things: one, most likely it is a gigantea and two, it has no zooxanthellae (yellow carpets with a healthy zooxanthellae population appear more brown or sometimes green). Bad news on both accounts because gigantea's have a *terrible* survivalibity rate from collection adapting into captivity, two, it's going to be something of an uphill struggle to eek it along into that zone of "adapted into captivity." Once there, gigantea's are beautiful carpets and tend to be rock-solid, easygoing aquarium specimens but the rough reality is that it's maybe 1 in 10 that will get to that point. I'm not trying to make you lose all hope, I'm sorry, but the flip side is there kind of really is no sugar coating this, carpets have horrendous survival rates and it's nothing we as aquarists can truly influence: either the damage is done prior to purchase, or some specimens simply don't have what it takes to adapt to captive life outside of the tropics. We don't really know why.
