There are 2 possibilities that I can quickly think of.
- Plant/dw not clean, shrimps felt uncomfortable and running to the top. This can be observed, if you noticed multiple deaths soon, or color run, etc. It's been 3 days since your first post, if there are pesticides, death would have occur by now. - A lot of micro-organism further up, so they are up there to feed on the micro-organism. There could be many other reasons. |

is the green pipe the outlet? if yes, then maybe the current is too strong. get a rainbar.
also, wat soil are you using? and what is the ph of tank.. did you wash the moss before putting in? there might be anti-snail chemicals that might cause the shrimps to be uncomfortable. get the rainbar and update us.. |
