New APHQ member Mattquaponics has posted a call for help on BYAP......here
To summarise, Matt has been keeping 100 silver perch (ranging from 120mm to 300mm) in an IBC......and they have contracted at least one disease.....with the likelihood that he has more than one problem.
He now acknowledges that this was too many fish but he was following advice when he stocked the system originally. Guess where the "one fish per 10 litres of water" nonsense comes from?
Matt has sought help from other BYAP members.....and (as if he hasn't already got enough trouble on his hands) has attracted the attention of one who, having consulted the aquarium websites, has prescribed a treatment involving Potassium Permanganate.
The first thing that his "adviser" should have told him is that he's not a fish vet and that, before putting anything like potassium permanganate into his system, he should consult one.......or, at least, he should be seeking the advice of DPI fisheries staff.
What Matt's "adviser" won't have learned on the American aquarium site from which he so liberally quotes (without reference) is that, diseases like those that Matt has encountered, are notifiable.
What Matt should do is:
- Euthanise the fish in the system.....and dispose of them carefully.
- Sterilise the system thoroughly.
- Equip the system with solids removal devices. Most of Matt's problems stem from high organic loading.....too many fish/no solids removal.
- Start again.....with not more than 50 fish.
- Consult more credible information sources on silver perch like this one.
Matt, I'm sorry that this happened to you. You're not the first and, regrettably, you won't be the last. See this unfortunate episode as a lesson in not taking advice from people who don't know what they're doing.
