My son bought 2 bristlenose pleco’s 3 weeks ago. We thought it was a male and female. He bought a long cave-like pleco breeding tube. Within a week the male was in there. He stayed there round the clock for over 2 weeks. This morning he left his post. My son dumped the cave into a separate divider for the babies. He had 4 left. I imagine the other community tank fish—mollies, angelfish, and tetras— gobbled the others up. If the 4 make it, that’s probably about the right number for now .If we wanted more in the future, what should we do differently. Sorry if this is a repeat topic. Thanks
