well, a week or so ago i rearranged the rocks on the left side of my tank. since, i have hardly seen my #1 male, who is due to spit the babies any day now, if he hasn't already. he's very tough to catch, as even the slightest movement sends him darting for the rocks.
I arrived home from work at about 1:30am last night, and noticed the female floating around with a partner. i turned the lights on, and the female took off, but the male kinda just hung around in the back corner, bouncing his chin on the ground as he floated. When I slipped the net in, though, he went for the rocks. He came out, and was swimming in the middle of the tank, and then went to the rocks on the left. As I put the net near where he was on the rocks, he swam away, but then came back and was popping at the net (more on this at the bottom). While appearing to try to attack the net, he basically swam into the it, so I scooped him.
While placing the net so the rim was out of water, but the fish was still in water, I grabbed him and tried opening his mouth (he obviously had something in there). He slipped, and spit a bunch of eggs! Yes, I said EGGS. From what I've read, I've always thought card's were livebearers. Guess again.
So, now I've got the net positioned at the top of the tank so as to contain the eggs, allow them good flow, but yet the rim is out of water.
On to the popping. This is a behavior I noticed earlier in the week. I've got a flame angel, and he pretty much claims the whole tank as his. He doesn't nip them or anything, but brushes against them to get them to leave the rocks. While trying to shoo the card's from the rocks, I noticed one of them was popping at him, like trying to tell firefly to back off. I could see him popping, but could also hear the popping. Pretty cool; at least, I thought so.
So, what did we learn today?
1) Card's are NOT livebearers.
2) Card's pop, as a warning system to other fish.
:D
