Fish re-homing centre Sorry guys but to me that sounds like the sort of company that collects unwanted furniture to sell on to those on low income . Sadly the prices they then ask for the stuff is beyond what a person on low income can afford.

Don looking at the picture you have posted , I can see what look like 3 large Sanke , those are the ones with orange on them , they alone could go for £100 + each. The white and black one could be a Becko , cant see the size but value could be around £80 + . The white ones could be Platignum Ogons an 8" one would set a buyer back around £35.

The goldies ( goldfish) anything from £5 upwards.

I have 2 ponds , one 300 gallon for my smaller fish and a 2000 gallon for the big boys , both sadly overstocked, if not I would have been happy to give you a price for some of your fish.

My advice to you is not to rush in to getting rid of them, as that looks like a nice collection. Although a friend and I run a koi forum I also post on a number of others forums, and would be happy to help you move your fish on.
And offer advice on keeping them alive until such time you can sell them.
