A fish is worth what you are willing to pay for it. I don't really do the FH thing because of all of the crazy junk they feed them.
They do this to sell them to you and after you get them home, they lose color because they are no longer being pumped with that steriod crap.
I grew some baby Midas out with Grand Sumo Red but it "says" it contains no hormones.
To answer your question, I wouldn't pay more than $25.00
