Sticklebacks of course cannot manage to plunder the gravel-covered spawning nests of the river trout, but they circulate constantly around the spawning ground. Roe grains that have been flushed out will be their prey and they are quite greedy for the roe. What more is on the menu? The larva of chironomids, tiny crustaceans and other bottom-living organisms. It may be useful to know that these little robbers even manage to devour hatched trout fry.
On the dorsal fins of the slim, oblong body of the stickleback spines can be seen – on the dorsal fin they may be nine up to eleven; on each ventral fin there is one spine. The thin tail stem of the sticklebacks shows clearly. The small fish are short-lived, up to three years; the length is rather uniform or about 5-6 centimetres.
For habitat they like rather shallow waters with spring water and it can be noted that they have even been found in drilled wells.
