I completely understand restricting the food would help reduce the amount but it's a 75 gallon with a ton of plants and it's where I put all my miscellaneous fry I'm not going to use for breeding. For example, ordered some platinum blue mosaic guppies, some turned out red, yellow, etc. I don't want them in my breeding population. Also I've got tons of red wag platy fry of different ages in there. I really don't want to restrict their food because they're still gorgeous fish and I don't want to stunt their growth. And I've done the "smashing them against the glass, picking out as many as I can but there's tons of them in there. And as always, thanks everyone for the advice.
