Well, I managed to catch all four the skunk loaches. Eventually.
As you know, I have a HEAVILY planted aquarium, which I did not want to break down.
As a starting point, I starved the inhabitants, and then tried various methods of catching the skunks.
I tried the inverted-bottle-neck method, and also tried putting a large 5L water bottle in the aquarium (both with food in of course!), but only caught kuhli and java loaches (Remember this for one day….). I even managed to catch the overweight, extremely crafty, Stoffel (False Siamensis). All but the skunk loaches.
I even made a trap using a net and a piece of string – this obviously did not work, but I was desperate by that time!
My LFS suggested I try using a snail trap. I must confess that I was skeptical, but realized that I had nothing to lose, so I bought it.
This is how it works: there are spacers that one can either leave in or out, which is determined by the size of whatever it is you wish to catch. (I left every second one out). Then you put food inside the red bait holder and wait.
When the fish swims in to get the food, he swims past the black, one-way levers, can’t swim out again, and he’s caught. This does not work on all fish though as the kuhli and java loaches were going back and forth as though these were swinging doors.
Sitting fishing for anything between 1 and 5 hours at a time, I eventually caught the skunk loaches. I managed to catch loach 1 after 2 hours on the first day. I set up a semi-quarantine tank in a 25L bucket with heater and power head. Loach 2 took a bit longer, and I caught him on day 4. On the fifth day, I caught the 3rd one, and saw that one had died. Must’ve been the stress.
The weekend saw a friend and I fishing for about 5 hours – to no avail.
In the meantime, I was dreaming of catching skunk loaches, tanks bursting, etc. It was very frustrating.
I decided to close all but one of the slots on the one side of the trap so as to limit the places for the last skunk to escape from and on day 7, #4 actually went into the trap. However, as I lifted it out, she escaped (definitely a female) as she was thinner than the other 3 had been.
On day 8, I asked God to help. (Should’ve done this long ago!) I got a brainwave and closed all gaps on the trap except one. Within ½ hour, she had gone in, and I quickly whipped the trap out. VIOLA! All 4 caught. That night I slept peacefully, and I don’t HAVE TO rescape.
And that, my fiends, is how you catch a skunk loach! B)
NOTE: my aquarium became rather polluted after this (all the excessive food that was used as bait), which lead to an outbreak of cyanobacteria (blue-green aglae). I have sucessfully managed to eradicate this with erythromycin - obtained from my local vet. Now I am doing loads of water changes to get the water quality back to where it was befofe the skunks came....
