I've just gotten back into freshwater liverbearers after a 25 year break. I'm going to keep guppies only. My daughter and I want to try some breeding, so I'm starting with a 20H tank and 6 male and 12 female store-bought fancy guppies.
I have read different ways to separate the mother and fry. I plan to buy a 10 gallon tank and use it for the breeder tank. Any females ready to drop will be transfered to this tank. I plan on using no gravel, and a sponge filter only.
I have some #8 hardware cloth (about 1/8" mesh). I thought I could make a mesh divider, the size of the tank bottom, and suspend it about 6-8" above the bottom, with the female above it. The mesh is large enough for fry to drop thru, but too small for the female to get thru.
Has anyone ever tried this? The hardware cloth is galvanized, so I am concerned about zinc and chromium possibly contaminating the water. Back before stainless steel became readily available, galvanized metal was used extensively for human food-grade food prep equipment.
I'd just like to hear if others have tried this, before I risk the fish.
