I recently bought 6 tiger barbs, one of their finds have been completley ripped off! He is still swimming around fine. Will they grow back, will he die?
Fins grow back just fine. Be sure to have good maintenance habits, with significant weekly gravel-clean-water-changes and good filter cleans at needed intevals.
Would be interesting to hear if you ever figure out whether it was the barbs nipping each other or if it was the silver tips or the RTBS.
