so I bought 5 clown loaches about 8 days ago who are still in QT in a 10 gallon tank. I still have not seen them, therefore have not really got to observe them... They are absolutely spastic and I think if I take the cave out that they hide in they will hurt themselves. I snuck up to the tank last night b/c I saw that 2 were out and when I got about a foot or 2 from the tank, they freaked out. They hit the walls and lid of the tank it was so loud, I could very clearly hear the noise of them hitting the glass !! I don't have a light on the tank, and there are a few fake plants, maybe some more caves or hiding spots so that they might venture out? Any other suggestions?
