I got it at Joann's (a sewing and needle arts supplies store), it's a plastic sewing mesh that they have in a couple different millimeters thickness, and sizes
me too - keeping my fingers crossed!I hope he recovers well.
Depending on personality, that could provide some nice hiding for Betta fishieThe tank feels very crowded now though...
This is what I was thinking too.$50 for fish in poor condition seems like a lot. Does the tank come with them? The females could stay together, and you could even divide the 5g if you had to (2.5g each is fine, on the low side but still fine). The 40g as a sorority tank could be a lot of fun. But I'd try to talk the seller down unless they come with the tank and it's in decent shape.
