Hello all, it's been awhile.
I set up an 18 gal hex breeder tank a couple of weeks ago. Since then two guppies, a red wag platy and a sunset platy have given birth in it for a grand total of approximately 80 fry . The tank is divided to keep them separate. (Most are being moved to LFS fri.)
Question. What is the best thing to use to put over the end of the gravel vac while the fry are in there? I tried some thin commercial sponge but it was still too thick.
Would netting work. Like on fish nets?
Any ideas would be greatly appreciated.
