I have 7 neons and one is being oppressed by the other's and made to stay in the back of the tank behind all the plants. I'm concerned it will stress or starve though he does sort try to come out during feeding. I've tried to feed back there, but my other fish are too smart for that. Would it be even more stressful for me to quarantine him until he gets bigger and stronger hopefully or should I let nature happen? I've got 10 harley rasboras also in a 33 gallon tall hex. Suggestions?
