Whilst there has been plenty written about overstocking , what about understocking ? Couple of days ago I lost a trout , his tail had been nibbled , the underside nearly back to his body , and infection set in. Bullied to death , poor buggar. He was one of three in a four hundred litre tank , last year I had eight in it without any problem. What do the experts reckon, chuck a few more in there or let the last two battle it out ? I seem to remember Bullwinkle having the same problem some time ago. Anybody know how He got on? Cheers |

What size are your trout? Are they all around the same size? How much are you feeding them? |

Understocking on fish means that you just plant less plants or put up with slower growth of more plants. |

arbe - those three ,one is bigger but not heaps bigger, about six inches probably getting 4 gms twice a day. I've never measured it but they look in good nick , even the one I lost. They are probably getting more on average than the others , but like I said I've never weighed it Stuart - plants are not the issue , and what you're suggesting is a different matter, in this 400lt tank 3 trout, 1 bullied to death (I think) . Last year I had 8 in it with outa problem , is my little problem as simple as that ? Thanks Guys , I would like to here your thoughts. Cheers |

I took some fish to someone in Perth the other day who already had two trout in their tank and one was chasing the other all round the tank. I put 25 more in there and I would expect that the problem would be fixed. I have similar problems here with the Silvers that I keep in cages, if the stocking density isnt to their liking they just hammer the weaker fish until it dies. |

Yeah the territorial tendencies do tend to come out if you only have a couple of fish. Apparently murry cod are particularly bad for that. Should have read the post closer. |

earthbound wrote: Sure it's not fin rot? Nah , don't think so , although he was pretty funky looking I think it was a result of being picked on. The offender has started on his next victim , I think I'll let 'em battle it out  So for future reference what would be a minimum number in a small tank to stop aggressive behaviour? |
