Not proud to say I've got some obese cories in another tankThat's what I thought about the barbels. But in some fish it's more a sex determinate as to barbel length. Some barbs come to mind right now.
Fat fish are healthy happy fish! Yours are not obese like some overeaters can be, just "filling out" in a good way.
Keep up the pics please, we love them!
But yeah. I do round out what they eat as well, offer spirulina flakes once a week, mostly insect based foods. They are good eaters, but have to compete with the harlies and barbs, plus the 20 loaches in with them too lol
