Just found my flame angel who I’ve had since early April laying on his side in the sand bed. He’s been active eating, swimming, model citizen for the entire period I’ve had him. Other tank inhabitants are still doing great, same with coral.
He’s still attempting to swim around or well flailing. Any ideas on cause and if it’s worth attempting to save him?
