Thats good to hear, then 🙂 … I couldnt see that they were small. I was just a bit surprised to see that different fish together.
I wont pretend to know a lot about the sewellias 🙂 it sounds like you know them much better. I just know that I had some at some time, and I wasnt paying enough attention to their different needs regarding flow of water.
So I didnt want to start a discussion for sure, – and I am glad to hear they arent supposed to stay.
The shrimps, yes for sure live in same biotope 🙂
