Penguin Tertas Attacking!

[nic420]

hello and help!
i have 4 pengunin tetras i my tank and they seem to be picking on the small one..i got home today and
noticed they have torn the fins and keep chasing it in to the corner...also my biger kribensis seem to be joining in on the attacks! and i fear there all just going to keep attacking the smaller tank mates!

how can i help my little penguin terta? i have another tank but theres a male gourami in that one and hes quite agressive to all fish..another tank that i have is a golfish tank but im sure it would be to cold for the tetra..
can i just keep the lille fellow in a tub or plasic box till his fins grow back and then re introduce him to the
comuntiy tank? or is it crule to keep him in a small container?

Penguin tetras are one of those schooling fish that need to be kept in large numbers otherwise they all batter the weakest or all fight to be the strongest I would suggest (depending on tanks size) to get an other 5 or 6 so you have around 10 or 12 in total and the aggression should get spread out enough for the squabbles to go relatively unnoticed amongst the individuals
