They are loosing scales one has quite a big patch of missing scales

Hi, I had 6 happy green tiger barbs, 3 died because of problem with my tank, which is all sorted now. I got 3 more and after a while I noticed the little ones where picking on one of the bigger ones, so I thought I better get a few more to stop the aggression so added 5 more and now all the new small ones are picking on all three big ones, is it because the are bigger so are different? they are in a big tank with some lemon tetras and rosy barbs, they ignore all the other fish, the aggression is just towards the bigger tiger barbs, any ideas?

Hi Caryl, the other tank is about 36 liters and has 6 tiger barbs and three peppered cat fish and they all seem happy and are doing fine, I will take the aggressive fish to the fish shop tomorrow, and I will get a bigger tank once the fish get a bit bigger... thanks for the advice I think the people at the shop try and get you to keep buying fish so they don't always tell you the right thing.

Hi, in the last few months I have started my first tropical aquarium and due to bad advice on what fish I could put in my tank I now have two tanks, tiger barbs in one and golden and rosy barbs in the other, I had 2 golden and 2 rosy, everything was going fine and then I noticed that one of the rosy barbs wasn't looking too well, it had lost weight scales missing and one eye missing! i couldn't believe it! so I watched... the other rosy is very aggressive and attacking it,( I didn't think the rosy barbs where aggressive) so I went to the aquarium shop for advice and came out with more golden barbs and 2 more rosy barbs (both male because they said that if I put females in the mix they are likely to be more aggressive)... they told me that there is less aggression when there is more of them because they do better in schools, I have put them in the tank and the aggressive rosy barb is bulling all the rosy's and they are all hiding in the corners, not sure what to do next except take the aggressive one out, but don't have anywhere to put it, also I have a 20 liter tank which now has 7 golden barbs and 4 rosy barb a total of 11 fish, which seems to me to be too many fish for that size tank but the lady at the shop said it would be fine. please any advice would be appreciated... thanks
