Keeping track of all the fish with screen shots is soooooo much fun! And sooooooooooooo time consuming!
I did it for a couple of months! Best I came up with is going with full tanks. Each fish with each fin, then vise versa ... each fin on one type of fish ... plus formulas on how to breed the fish, but only 'one' way. There are so many ways to get the fish I decided not to even attempt to keep track of 'all' the ways!
Keeping track of breeding is definately the only way to go to find all the fish!
I ended up with 440 .. and of course had to go back and find that 'one' that I'd missed!
Silly world. So many folks having so much fun with so many fish. .............. Sure is a nice break from reality!
