Hey all,
Bit of an issue in my 40-gallon with fin-nipping at the moment. Certain fish are missing chunks of their fins. I've noticed this on:
Endlers (mainly the immature Endlers, but the females also show some small nips taken out. The fry and males are intact).
Boraras merah (only a few, though one is missing the entire bottom half of its fin).
Neon Tetras (only some of them show screwed up rear fins though - a few have perfect fins).
I think I can safely say the Endlers and Boraras aren't behind this. Neither is the Kuhli Loach, the Cories, or the Otos. This leaves me with two suspects.
1. The neons themselves. I know they can get damned nippy. Their own fins were perfect up until a month or two ago.
2. I recently introduced a pair of red-lined Killifish (Aphyosemion striatum) to the tank. They aren't a big Killie (max out at 2 inches), and the LFS warned me that they may swallow any small fish they can fit in their mouths near the tank surface, but they're roughly the same size as the neons now. I also haven't seen any aggressive activity, and most importantly, the first few fish with missing fin chunks happened before putting the striatum into the tank. I can't find any information online about the striatum being a fin-nipper, but I guess keeping them with such small tank-mates is somewhat of a rarity.
Anyway, if anyone has experience, let me know.
