There's never been an issue with the parents eating their fry... In fact, we have several generations sharing the tank, and there's way 2 may guppies 2 count (200+), lol. Aren't Plecos supposed 2 strictly b algae eaters tho? I know by watchin him, that he eats whatever algae is on the glass, cleans the plants/rocks & ornaments. He has never acted in any way that would make us fear for the safety of the guppy community, which is y we r wondering if, while siphoning his grub, he isn't accidentally sucking up the tiny newborns.... Idk, maybe a blessing in disguise?
I feel there is a bioload issue, but every time I've tried explaining 2 my mother-in-law that her tank is seriously over-crowded, but she shrugs it off. She says I'm just a "know-it-all", and refuses to listen to my advice, cuz her tank has "been just fine for 5+ yrs... All I do is feed em & they do the rest". What am I supposed 2 do.... I feel sorry 4 the 200+ guppies & the poor Pleco!
