I have recently bought a hundred litre tank. I have 5 platies, 5 scissor tails and 2 golden algae eaters. I also have lots of unwanted snails. It seems that these came in to the tank on the plants - i now know I need to awash any new plants I add. I have bought some chemical to get rid of the snails however this hasn't worked and the number is increasing by the day. Does anyone have any suggestions on how to solve this problem. I also have 2 algae eaters. Both were the same size 6 weeks ago - however one is now roughly six times the size of the other. I have noticed a baby platy this afternoon and was wondering if this increase in size could be due to an extra food supply? Do you think this growth will continue and such a rate and does this fish have the potential to be threat to the other fish in my tank? I would be extremely grateful for any help - especially as the guys at the local shop don't seem that clued up.
