Well, I gotta say, it was worth the wait, even tho I almost missed it ! Here's a little background: I have had 2 male L400s for over 2 years. For almost as long I have been looking for a coupla 3 females. About 2 or 3 weeks ago, I won an auction on AB for 5 adult (3m/2f) 400s. They arrived about 2 weeks ago and I set them up in their own tank with my 2 males. I figured they would need some time (I thought a few months) to settle in. Wrong ! The other day (Sunday) I was doing my weekly water changes, and I'm vacuuming their tank, getting the mysis and brine shrimp I had fed them the day before. Then I look closely at the vacuum tube, and holy crap, something is swimming in there ! I quickly shut off vac, and down swims a tiny little white pleco with his/her egg sack still attached ! I still think I vac-ed a couple up and down the drain, but I don't know for sure. I found 1 more that was dead, and so far that is it. I never saw eggs, or more than 1 fish in a cave. And I never expected it to happen so quick ! So I have at least 1. There may be more because my caves are pretty tight when the males are in them and I can't see around them. I'll keep an eye out. Too soon for a pic (I need a better camera, too ), but I'll eventually get some. In the meantime, here is one of the original males. I have no idea who the mom and dad may be. Guess I better wake up and get with the program !
