i'll get pics later. i think my most expensive fish in the tank are my fontosa. i have one huge one and 3 little one. the 3 small one probably worth $25 each and the big one probably $75-$100. the rest of the fish are under $20. when you buy them small they are cheaper. i have mine when they were a baby. now they are pretty good size. these are tropical fish btw. your buddy probably have the salt water fish, those are more $$$$ plus it's it takes more work to maintain the tank too. i used to have boa constrictor before i got into fish. was kind of cool feeding them rat and sometime rabbit. i had 2 argentina boa over 6 feet long. when they got bigger their food got more expensive that's why i got into fish plus it's cool watching them swim around and chasing each other
