That's too bad, How did it happen? I could see fins like that getting in the way.
Mine seems to be adapting just fine, and had a voracious appetite tonight. I had to plop some flake food in the middle of the aquarium where the current is almost neutral for him, after the first batch which the Harlequins quickly devoured. They had bloodworms last night, but he didn't get as much as he'd probably like. This two stage feeding is something I think I need to do every night.
