Ratfish
Feeding Rat fish can keep the aquarium clean, but rat fish are naturally fragile and like to hide in dark places, which will inevitably make the aquarium a little dry.
1. A brief introduction to ratfish
Ratfish are native to South America. Ratfish can be found in almost every main and tributary water system of the Amazon River. This kind of fish is named "rat fish" because it has two cute little "beards" growing on the left and right sides of its mouth, which resemble small mice swimming in the water.
2. Choose a strong ratfish
The most taboo ones are those with serious protruding eyes and extremely thin waistline to tail. The best ones are those with complete beards, dorsal fins, pelvic fins, The tail fin is complete, the body is well-proportioned, and the swimming posture is normal. This kind of fish is relatively strong. However, if the fish is ordered from a fish dealer and is generally transported over long distances, the condition will not meet these requirements. Don’t be too harsh. Basically Just arrive. As long as the water is good, the rat fish is relatively thick-skinned. As long as the water is good, it will recover quickly.
