Excuse me, how to take all kinds of snails, especially flat snails, out of the straw vat?

Cut the leaves directly without feeding.

Turn off all the lights, including the indoor lights, and it will catch it when it climbs to the top of the tank. Snails always reproduce and survive because of the food left by aquatic plants and fish. Get rid of all the aquatic plants-every leaf should be cleaned (there will be many transparent eggs). If it is too serious, I'll just cut off the leaves.

Reduce feeding if necessary, and temporarily stop feeding 1~2 days ~ When there is no food source, it will naturally climb to the tank wall and be easily caught. It is best to clear out the whole tank, and then find a container to put all the bottom sand in, so that snails will all climb to the wall of the container when they are filled with water and placed in the dark.

Snails are mostly brought back to the tank from the bought aquatic plants ~ so it is better to simply check the place of the bought aquatic plants before going to the tank. I always put aquatic plants in containers, clean them and put them in the dark. If there are clean snails, they will climb to the wall of the container, so it is easy to catch them.

Extended data bait snail control method

Prepare some sweet potato leaves and blanch them in water, not too rotten or too hard. After cooling, put one or two scalded leaves in the corner of the fish tank and let them stand (don't put them in the place where the current is too strong). After 4~5 hours, shrimp and snails will gather together to eat. Let them eat. After a day, you will find snails of all sizes gathered on them. At this time, all you have to do is gently clip them up with a straw clip.

The actual effect is ok. I didn't see with my own eyes how the killer snail ate the flat snail, but after using this, there were almost no flat snails in the tank for a few days, only a lot of empty shells. The flat snail is a little small for the killer snail, so I suggest buying a smaller killer snail. By the way, killer snails climb n times faster than ordinary snails.
