I could do an estimate for my current fish stock-that won't be as bad...
Albino oscar-~$8 I think
Ornate poly-$40
Sev-~$2
Flagtail-$18
Syno-$8
2 clown loaches-$15 for both
SA lung-$18
5 glowlights-~$10
3 cories-$15
2 festivum cichlids-$5
Uaru-$12
=$151 not really that bad, but since I've been in college my collection has been pretty limited. A few years ago when I had 11 or 12 tanks running, I had easily over $500 in fish.
For my new 150, I'm sure I'll be adding another $100 in stock at least
