They hide really really well.. To the point that you can take out all of your ornaments and still not find them.
I had 2 incidents I wanted to share:
- One time I took out a ceramic log that I have to clean it and wound up finding one of my loaches swimming in the bucket I put it in. Luckily it was fishtank water and he was ok. He had hidden so well inside of the log that even though I looked well I couldn't see him.
- The other time was more tragic. I used to have a UV
filter and the flow lid fell off leaving the inlet unprotected. One of my loaches got in and ended up tangled in the rotor.
Loaches tend to hide if their school is smaller than 4-6. The more you have, the more they'll stay out, but the more space they'll need.
I was unsuccessful at keeping loaches in my tank. For some reason they would all end up dead even though my water is in good, constant shape..
Such a nice fish to have though.
