I just brought home four hillstream loaches! I've been looking for a few since last autumn, since they are a species that lives in the same stream as the White Cheeked gobies that I have.
These poor loaches, the associate that I got to help me was on his fifth day of work, and just didn't know how to use a net properly. It was a very stressful ten minutes to catch all four, and at one point when he was getting a little brutal(annoyed most likely), I told him he was giving me anxiety. He was like Yeah. Because he probably felt the same way.
Anyway, the last loach climbed up the glass and jumped into the other tank. Then after being chased with a net, climbed back and jumped down back into the origonal tank. They climb Above the water level! I was impressed, and glad I recently purchased a new glass cover for my tanks. I put my loaches in a betta cup to float since the bag was deflating. Lo and behold by the time I came back an hour later I only had 1 loach still in the cup, the rest had clambered out.
So I now have four hillstream loaches in my 40 gallon, with my mountain minnows and gobies.
Be the Better you.
