Hi,
I have got 2 headlight taillight tetras and 2 red phantom tetras that are quite pale and have poor fins, I wondered if some of my other fish are nipping them. I have 6 of each variety of the effected fish and the rest are perfect, the 4 fish that are effected would be slightly smaller than the others (of their variety). The tank is 450l and has 4 opaline gouramis, 2 golden gouramis and a kissing gourami in it (+ many other smaller breeds including neon tetras, sae's, bronze catfish etc)
What is the problem?
How can I help these fish? (They are quite reclusive, and stay in one secluded spot for vast amounts of time)
