hold on, if you have sunfish for long time, then why the sunfish hasnt grown up? You said they're 1 inch long....its sign that you stunted them, probably from being kept in smaller tank. Your sunfish should grew up 2-3 inches by now. Dont get pictus catfish till you deal with your albino and sunfish. if you want pictus then get rid of albino.
Focus on your sunfish right now if you want raise them, then they need more space to grow properly and hopefully they will probably live by the spring time.
And i have doubts on "my teacher bred sunfish"....sounds like he bred them in natural ponds...so he dont bred these sunfish but netted the sunnies out of the ponds.
Why your friend want build the pond under the deck?
NO MORE FISH! TILL YOU DEAL WITH SUNFISH AND CHANNEL CATFISH. PERIOD. and if i were you, i better listen to your mother as you have really limit space for more fish.
You dont learn from the past threads....always research them first before get them! You hasnt changed...just like leopards dont change the spots.
