I have questions for people who keep muti-thousand gallon tanks.

How do you catch fish when you need to? How do you deal with tank-wide issues?

I think I know the answers, but I'm asking anyway.

I have a large tank that's been up for about a year now. I found the first sign of a problem on one of my loaches over the weekend, a light grey spot on its side. Medicating the whole tank is impossible, so I tried to separate this one fish. I could never catch it. I bought a bunch of throw nets and tried dividing the tank up in small managable sections with net curtains to catch this fish. All I managed to do was stress out all the other inhabitants.

So I'm back to my original plan, of just letting things run their course as there really isn't any other options. Is this what you guys do? Just keep parameters as perfect as possible and let things go their way naturally?

THings I'm not really willing to do: med the whole tank, or empty it to catch one or two fish.
 
same problem here...altghough the problem with catching my fish is the possibility of them breaking the tank.....,.
 
setup a soda bottle trap for your loach
 
I've both used a cast net and the "net curtain" or impound net that you had mentioned. For the curtain, I used window screen (from a 12ft roll). I wrapped it around some swimming pool "noodle" toys (long round closed cell foam floating toys). For the bottom, I wrapped it around a pipe to weight it down. Movement of it needs to be very slow so that the fish are not spooked or stressed. When they were impounded I used a large dip net to catch them.
 
just curious...How big is your tank?
 
my friend uses blankets then roll them in,its really hard to catch large fish cos it might injure itself specially elongated ones like arows and knives
 
empty your tank to a certain level. that should help you have better control when catching the fish. also you can corner the lad and remove any accessories in the tank which might bother you
 
No multi thousand tank but when we moved my 30" niger cat we had to use a big landing net and drop the water level.
