I gotta go cheap with this one. maybe $50, unless a really nice salt. the fun for me is catching them. and that this can be a cheap hobby and still be enjoyable.
just to bring back a dead thread.. one that i find rather interesting...
i've spent $150 on a 3'' jawfish... i guess the absolute limit would be how much i really like the fish, but DEFINATLY nothing over $1,000* (no snow aros for me )
basically a dragon moray is what im taling about... if i ever have a grand to blow (yeah right) then i'd consider one if i had a tank for it
depends on the fish, if it's something a want real bad, that is really rare, or a i haven't seen in the long time, i'd rather not limit myself. But up to this point on a single fish is $850.
