Sometimes I think having more tanks would be a great option, BUT... half the fun is figuring out how to do what you want within the limits. (hmmm, does that say something about my personality?) Anyway. In one of my tanks I've found all the magic fish, in the rest I'm experimenting with different combos and keeping track. celebane? I think? has created a program for keeping track easily. THANK YOU!! My hubby thinks I spend WAY too much time on this game, hehe. I also have found a chart, I think it was on another site, about how to figure out what you will get with what. I'll post it, but I'm not entirely sure of the results since I'm still testing it myself, so far it seems to be working.
