30 gallon unfiltered tub

Hi all,
I have a 30 gallon tub out back here in mid-missouri. It gets sun for much of the day and temps have ranged since I've had it out and stocked (white cloud mountain minnows, pink ramshorns, bladder snails, yellow shrimp) from 40-98! All animals are healthy and breeding. No filtration or air movement. I have done just 1 50% water change in the 2 months I've had it up. I recently added 4 Danio choprai. The minnows have bred like crazy. I have som sort of palm/papyrus, water hyacinth and anacharis, plus some floaters (duckweed and fairy moss)

I thought about it, but I think it'll hold as long as it doesn't fill up any further. When it gets too high after a big rain, I dump a bit out. You think it might split open?

That's a great idea, Nicole. I'll look for that tomorrow at Lowe's.

I totally forgot you had it! Yes, I want some! Let's FB a meeting time.

Well, now I have some frogbit! Thanks, Gary!
I struck out on the fencing, Nicole. I'll look for some bungees soon. I set-up a second one see what my pair of Pseudomugil Gertrudae do out there. Maybe I'll put out some blue shrimps in that one. The yellows seem to be doing well out in the other.
