Hi guys..not sure this is really the right forum as I don't consider myself a total beginner to the hobby, but oh well
I have three clown loaches in my tank. Usually they're active the whole time..swimming up and down the glass and clicking away. On Tuesday I noticed that only two of them were going into a frenzy at feeding time (once daily just before lights-out)... the third (fattest of the trio and most dominant) was nowhere to be seen. I went and got a torch and had a look in one of the completely dark caves under my driftwood, and there he was, lying upside down (before you mention it I know it's common for these guys to rest in that position!), and looking like he was just chilling out.
Next night he was in the same place, and every night since then.
I'm just wondering if other people who have kept/keep Clown Loaches have ever experienced one of them suddenly deciding to turn into a bit of a loner and not come out for food. I'm mildly alarmed by it...but can't see any sign of Ich. All the other fish in the tank appear to be completely normal. So yeah.. any comments?
