have any of you ever had trouble finding the perfect fish for yourself? i mean its personality and such. i started out with the typical petco stuff then jumped into aros &ck's, which were very cool but too much for myself. my fav. fish currently are my sailfin pleco, clown loaches,sd's and a couple varios cichlids. i have a tank full of rbp's that i regret getting only due to the fact they arent the most relaxing and enjoyable fish to watch. anybody have any suggestions for that great family "pet" fish, if there is such a thing, that might go well with my previously stated favs.? maybe an oscar, nothing over 18". thanks
