Help, Tank full of sick fish!

It looks like you have possibly a bacterial or fungal infection of the leading hard dorsal ray. Pimafix and melafix together will cure this.
Dont stress these sort of things are easy to deal with.
HTH

iv added some melafix and pimafix, ill let you know how she is going if anything changes! thanks guys, this is a great site, everyone on here is helpful and actually knows what they are talking about (which is alot more than i can say about some other forums). your help is greatly appreciated =)

be careful with the avitrol liquid - i used this and it caused a massive bloom in our tank, luckily didnt lose any fish, but i suspect it may have glucose in it? we have birds aswell, so its not wasted lol. Best bet is the tablets

the discus people use one called Sykes Big L pig and poultry wormer which is supposed to be good also

How did you go colsha?

yeah he is doing well, his fin is growing back, i think during the process of moving the fish from q tank to tank, his fin must have been injured in the net! im in sydney for a few days so i hope he's better when i get home!

Thats good, hopefully will make a full recovery.
