15 gallon set up ideas?
Here's the story. I made the mistake of saying to my DH that I thought I might like to have some fish again. He mentioned it to a friend of his who does the backyard aquaponics and has bunches of small tanks that he's "outgrown", so he said that sure, I could have one, he'd be glad to get rid of it. My birthday came around shortly after that, and I'd kind of moved fish-getting onto the backburner because of the rest of life getting in the way. DH and I want to go out for dinner for my birthday, so the friend offers to babysit my Stepkids for the evening. When we come back to retrieve them, of course they're bringing a fishtank home... With four fish. Two tilapia (from the stock that Friend raises to eat) and two convict cichlids... in a fifteen gallon tank. At this point, they're about 1.5" each, except the smaller convict, so I figure I have some time. And then... They Grow. So now I have Greta Garbo, the smaller convict who hasn't grown very much at all; Mel Gibson, the larger, more bullying convict who gets bigger every day it seems; and a pair of Aquatic Turkeys that I would have much preferred stayed with the Friend to end up in a taco. The tilapia and Mel are coming up on 3" each, if not larger.
We recently got ourselves a new, nice setup, 37 gal with a stand and a proper tank cover and lighting and a couple plants that the LFS said might withstand the destructive fish I have and all that jazz. It's currently being cycled, fishlessly, although I did throw in a handful of tiny snails from the LFS just to see what would happen. Mel will probably kill them when he gets introduced in a couple of weeks.
So what I'm wondering is, does anyone have any ideas for this little tank? Step-son has expressed interest in Angelfish, but everything I read says that 15 is too small (even though I recall as a child keeping an Angelfish in a 15 gal community tank with no problem, but maybe it was a small variety?)
I, personally, was thinking about a betta fish with a few other small community fish. Thoughts?
