I had an albino pleco (unknown origin, it was caught in a shrimp net and raised for awhile in a lab at UW until I rescued it) in my 75 gallon Tanganyikan tank. Not bristlenose. I decided to liven up the tank and add a bristlenose. Went to LFS and got one that was slightly smaller than my albino (4"). They seemed to get along just fine. Noticed the BN in an artificial cave for several days, wouldn't come out to eat. I shined a flashlight in there last night and saw lots of little wiggly tadpole looking fry! I pulled the cave (with dad and babies and water) and put in a 12 gallon holding tank I keep for this sort of thing. Mom has been eating OK but she had a concave belly a few days ago, seemed tired. Now I know why. Now I'm not sure what to do next. I can't keep all these babies once they start growing out. I can't put dad back in the main tank because this will happen again. There are only so many LFS in Madison I can try to give them to. And I am out of town during Cataclysm. I know I could have left them in the Tang tank and let nature take its course (that is how the Cyp population is kept under control) but now that they are out I can't just put them back, knowing the consequences.
