Theyre plastic, but they don't mind. I went with these as ive got no light on their tote.We're having very HOT weather here now...maybe just a cool down WC or 2? Yeah, I know you live far away from me...Rain or storms on the horizon? You know they can help get them in the mood!
Are your fake plants "silk" or plastic? I have some ancient plastic 1s that seem too scratchy, but corys are "armored", maybe they don't mind?
However today, they've started chasing the female around, which is a very good sign. Just had a major cold front move through last night too.
