Been there, done that !
Was just staring into my 50g thinking 'if I I take those 2 back & get 12 more of those & maybe one each of those , then I ll be happy with the tank'.
I have 3 50g & only one of them is 'done'. Love this hobby!
^ haha yea that's why how I've bought most of my other tanks. There's always that fish at the store you just can't pass up. And that fish always seems to be the one that isn't compatible with anything it seems like for me.
I have been messing with fish for over 30 years. There are a lot of more common, easy to breed, fish I just never got around to spawning. I've done some really hard fish to spwan and at this time looking at going back and working with the easy guys. I actually had a pair of Belonasox in the early 1980's -likely before most of you-and just recently got another small group. Very cool and better than I recall.
Yes, I have definitely felt that uneasy feel of being unsatisfied with inhabitants after doing all that research and such.....its a bummer sometimes because you feel bad taking them back to the lfs but you don't want them either.....
Current tanks: 55g/ 40B/ 20H/, 5g If you always do what you've always done, you'll end with the same results
