My LFS gives 1/3 store credit. If you got your fish cheaply, it can be a good deal because this place has high prices on their own fish ($40 for a 2 inch EBA, $100 for a gold nugget pleco).
I’m looking to downsize to 25% or less of my original stock and should I have to give them to my lfs I’m expecting about 10% of the value for the more higher dollar fish (I’ll be damned if I give them to my lfs for that, I’d rather give them away for free to aquarists I trust) and less for the more common fish.
Depends on the fish store and fish really.
I bring my fish store 3 types of fish. Two they give me 20% store credit and one they give be about 16% store credit. The percent is based on what they sell their fish for
My favourite local shop gives me 40 - 50% of retail, depending upon species. This is strictly credit; I have never asked about cash. His retail prices are very good, so this credit is likely about 25 - 35% of what these fish would go for in most other shops.
I am in South Carolina, and my LFS told me there legal problems with giving cash for the fish. Some sort of tax thing I think, but I am not if that is the real reason.
We used to have a LFS that would trade for cash if you talked with the owner, but it was always under the table stuff.
