I got some eggs about a week or so ago which got a case of fungus. I've seen them courting for ages, so I'm guessing its a matter of time before I got some more... if I haven't already (7 bichirs in that tank sometimes with full bellies)
As for the pond, its about 3" thick right now. I had to chisel my pond filter out 2 weeks ago
Luckily I have this one to enjoy year round
