I've had this Jar for a while. it held plants for me... and I had recently emptied out most of the living contents except for some dying scraps. The tannins are from a piece of DW i had in there.
I think I filled it 3 months ago to hold moss...
So the amano story:
Well I got an amano to see if he will eat some algae for me...
I have a non covered tank for my betta ( he can't jump even if his life depende on it...)
The betta doesn't jump, but when the betta chased the amano, the amano sure lept!
this all happened whilst I was at school...
So I found this crispy amano on my carpet. I was going to bury him... but i saw the brown jar of water I've was going to pour out. So instead of buring the poor thing, I tossed the crispy mano in the jar.
two days later I decided to pour out the water with said amano's decaying corpse...
I ended up almost spilling the contents on my carpet when a shrimp lept out from the debris...
o_O it survived....
and...so I left it in there.
It's been two weeks now and zombie amano looks as good as new.. in his own little filthy jar....
There's definitely an eco system in thy jar as There are many many seedshrimp dorming with the survivor amano right now. As to how that eco system works...
I don't have a clue. there are more dead plant matter than alive plabts in there
