Backyard Aquaponics
A place to discuss aquaponics

When I offered excess fish to an aquarium shop owner he was enthusiastic. But when I told him that they were now in a large pool, he told me that the adjustment is difficult for fish and could be fatal.

Is he right? I'd be grateful for comments and advice from members.

strange............cant see it being a "space" thing, much fresh water ornamentals are wild caught and pretty much all marine i think.

only adjustment i'd think needed is to ph and temp.

maybe they're concerned about that?

measure your ph and temp and give that to them.

i think aquariums usually run their tanks at about 7.0 to 7.5 PH temp.

I can`t see any problem either.
If you acclimatise coldwater fish to a warm water aquarium they can die if reverted. You`re going the other way so the fish should be fine if the temp/ph changes are made gradually.

Offer to put them in an aquarium for a few weeks before you supply them.

Steve, Hex, your wise counsel is appreciated.

I often change fish from tanks to dams and ponds and visa versa and never have any problems. It actually surprises me how well a fish suddenly adapts to life in a 4000L tank after having just spent the last 6 months swimming around in a 2000m2 pond. Im about to fish a few trout of my dam which have just spent the summer in its cool depths and move them up into the tanks again.

Think you are in a 'negotition' stage with the owner. Possibly more about price than anything else. (Not sure fish have a long term memory, as in "I remember when I was younger and you could flick your tail 200 times before you hit something hard".

I aam getting confused ... I thought I responed to this ...

anyway ... Adrian , gimme some mollies for school and I will vacate one of my tubs and see if they can relocate...

I think no prob at all...

they are a very robust little fish!

Anyway .. a couple of dozen in a mini AP system should be no prob.


In fact I think fish living in the large pool environment that you have created would have more chance of being immune to a wide range of common diseases.
