Having a few pond issues and lost another fish today, I'm very aware that with my current setup I can't do a prolonged quarantine on any larger fish. Therefore I'm looking for a semi permanent solution. I've seen the IBC containers farmers use, about a meter square, and suspect they'd be fine with some modification (i.e. an angle grinder!), alternatively depending on shape I guess anything over 500 litres may suffice. Does anyone know of anything locally? The ones I've found online want more for delivery than for the items themselves and transport anything other than short distances may be an issue for me.
