Weird! I havent put any rocks in my tank, besides gravel. I have wanted to try doing lava rock though. It's very porous, supposedly can hold lots of BB, and I imagine attaching plants to one, would make for a really good nutrient root delivery. It would have to be large though, lava rock is pretty light.
I do have a couple of the bendy lead weight things, and was using them for a bit of hornwort. I have them on my 2 new plants now though. I really didnt like the look of the black pots stuffed with cotton, in my tank.
I'm not sure if I have "high light" but probably not, since I'm not using metal halides or anything. I have the fluorescent, 18", and have a 50/50 actinic bulb in that, and then my DIY LED strips under the hood, total of 12 feet of those, but they were a cheap tape light, no PAR value available. It's funny though, I thought I did not have a green thumb, and I probably don't, but it's certainly not black, cuz I havent killed any plants yet, I have not dosed fertilizer, have no desire to do any co2, but all my plants do well. Except moss balls for some reason, so I guess I did kill two of those...
Anyways, I have the wild types in the tank with the yellow now. And I put all of my RCS back in the main tank, since the population went pretty nuts pretty quick. I think the tannins did it, cuz I put driftwood in, and they went like bunnies. But yea, the male just runs all over, swims in powerhead current, chases guppies (playfully, just following, not chasing in a threatening way), and mostly does his own thing. The wild female tries to pick at food, she LOVES snails eggs, which is AWESOME! My yellow, just chases the silver female. Everywhere. Sometimes she just follows, and sometimes she chases her very quickly around. But that's about all they do. Never seen them headbutt or nip at each other or anything.
I did tear the entire tank apart, and redid most of it, before putting the new honeys in, to try and make it like a "new tank" so they would have to all set up territories. I think it worked, because my yellow hasn't been hanging out in her normal spot anymore. No one has, as it has changed and it's now an open spot.
I'll put some pics, you guys can tell me if you think there are enough hiding spaces for them, or if I need to grab more hornwort from the other tank. Or maybe finally pull the trigger and buy frogbit online, lol.
