Let's see . . . my original plan was, when I move, to do some musical tanks.
Fish in 20gal go to 29gal
Fish in 29gal go to 55gal
Sparky goes to something bigger. I was almost thinking of getting a 200gal tank (or something that is 4feet or longer) and dividing it. I know, sounds weird. One side for Sparky, one side for cichlids or something. Overpowered canister filter for each side. If I did, maybe the congos could go with the cichlids. Then I can get goldies.
Or I should just be content with my skittish, nervous koi and comet goldfish whom I never see. -___-
I can dangle my hand in the water until it goes numb from cold and they just skulk on the bottom like plecos. If I want to actually interact with them I have to drain the water until there's less than half. Then I can actually reach in and touch them and they're like "What? Why you touching me?"
I think it's because they were all tank-raised and not raised in big vats. All the koi I see who are in big vats know how to come up to the surface to beg for food but mine don't.
