Thanks for the response guys and as for worming I deworm the tank once every 4 weeks I used to keep discus and have carried on the practice with this tank
Used that many times also I actually have sum here iv never been impressed with it but mite give it a try again at the weekend. To be honest though I dont think the lack of growth is down to external parasites im starting to think that maybe my water hardness could be something they dont like
So do u recommend giving them a dose of both ?
