Well, we'll see how it goes with the angels, but I'll definitely keep an eye on them.
And yes, that's his tank. He's had a lot of goldfish in there before and they don't really eat plants. Mine don't, just the floating plants (like duckweed) and the leaves that are already dying or dead. He had a lot of broad leafed plants in there, so the goldfish usually don't find them appetizing. Everything thrives in that tank. He grew the jungle val to 6' in less than a year and he's had fish reach they're full size very quickly. The Raphael catfish, for instance. It was only a few inches when he got it and now it's full sized in, again, under a year. I swear you could use that tank as a permanent grow out tank for any fish. Haha.
Still, he has a lot of tank ideas and a lot of them are already happening. We'll see how everything plays out when I move in. :)
