unfortunately at the moment i have a key hole angel and all it has eaten in 2 weeks has been off the live rock. 2 days ago in the morning i saw load of white spots, but by the afternoon they were all gone. could be itch.
however on the itch issue, i introduced some live rock (more food) that looked suss, right after the keyhole was added, so it could have simply been bad timing.
however i had an ebels angel once and it ate like a pig, could be just the type of angel you get.
good luck and welcome to 3reef. |
