smalltimer,
That was the best darn advice I have heard yet on the subject!
I had to get a pair of clowns out tonight for treatment and tried your suggestion... man let me tell you... I have tried getting them out before and needed to rip the tank apart and still spent 2 hrs chasing with the net!
You made it so easy I laughed out loud like a madman... I found myself taunting the poor fish in it's transport receptacle, <B>"What?!? That's all you got?!? - Yea... thought so, there's more where that came from!"</B> - Yes we're talking about my ego inflating over a slaughtering victory between me and... a fish, no... fishes.
Anyways here's how it went:
30 mins after zero light was established in the tank, flashlight on... <B>blip!</B> One fish out.... 15 mins more of pitch blackness... flashlight on... <B>blip!</B> 2nd fish out! easy as that..... I couldn't believe it... (well... more or less - point is... it was easy).
Now as Iechy mentioned... this isn't easy when your fish are hiders at night. If they are... well, this is still the way to go... I found that by flashing the light on and off every 10 secs or so I could "confuse" the fish and he would stagger out... Down side to this is, too many tries to get the fish out... and you will have to go lights out again for 30 mins or so....
If you need to get a fish out GIVE THIS A TRY! If it doesn't work, don't worry... you can still rip your tank apart...
