Nekoliko puta sam bio u situaciji da bezuspesno pokusavam da "ulovim" ribe u tanku, jureci ih sa mrezicom kroz gusto bilje. Mislim da ne treba da opisujemkolicinu frustracije i stete po bilje kojeovako nesto moze da napravi

Ha ... evo resenja! Doduse nema slike, ali dosta je lepo opisano, tako da nebi trebalo da bude tesko napraviti. Nisam bio u prilici da isprobam ovo, ali cini mi se da je dobra ideja ...
Catching fish in densely planted or well decorated tanks is a difficult affair that can lead to lots of stress for the fishkeeper and fish, as well as some serious damage to all of the landscaping in the tank. Many folks have their own bag of tricks, many of which depend on the behavior of whichever fish you are keeping. Some will have nets already in the water, then put in food so that the fish will come to the surface and be caught by waiting nets. Others will put food into nets to lure the fish in. Many fish seem a bit too wary for either of these net tricks, however.
The least disruptive way to catch fish out of a tank is by trapping. The best trapping method we know of involves clear plastic bottles. Here are two variations on this theme, both of which we have employed with success.
1. Standard clear plastic bottle with inverted top. This method has been written up in many places, including online on the Krib, and in an article in a past issue of the Apisto Gram. You can use small clear plastic bottles of spring water (the kind that come in four or six packs) to make these traps. The labels should be stripped off, as transparency is important for success (at least for visually-oriented fish). Remove the bottle cap as well. After removing the label, cut the top off the bottle just below the base of the taper. Poke a few small holes (with a pin) in in the sides of this top. Invert the top back into the bottle. At this point you can bait your trap. We find this is most conveniently done by partially filling the bottle (by submerging it opening side up in the tank), then adding the food. With visually oriented fish, live food, such as live brine shrimp or baby brine shrimp, usually works best. After adding the food, completely fill the bottle with water. Those little pin holes allow the escape of those last pockets of air trapped between the inverted bottle top and the sides of the bottle. You can place the bottle in whatever place in the tank you desire. Many fish will have preferred areas in the tank they hang out in. The trap can be placed at any angle desired. One can even float the trap (by leaving some air in it), although one would have to improvise something to keep the trap in place.
2. Baby bottle with inverted nipple. For very small fish, such as fry you can use a converted baby bottle in much the same way as a spring water bottle. As with the spring water bottle, make sure all labels are removed. Cut a hole in the nipple tip to the desired size. For fry, you can generally make this hole small enough so that only the fry can swim in (too small for the adults). Invert the nipple tip, then secure it with the screw ring. This makes a nice trap except that on all brands we've seen, the screw ring is opaque plastic, so it present a bit of a vision barrier (in contrast to the totally tranparent spring bottle trap). Still, we used this trap with great success for cichlid fry.
Both traps usually catch fish within a few minutes. About the longest we've ever waited for a fish to be caught is a half an hour. With the inverted bottle top trap, be careful removing the top when getting the fish out. Some fishkeepers have killed or injured fish by accidentally mashing them in the space between the inverted top and the bottle side.
We have the trapping technique on dwarf cichlid adults and fry in densely planted tanks. I do not know how effective this technique would be for fish such as bristlenoses or otos. I suppose one could but some zucchini in the trap and find out. When o
