Traffic light fish can be mixed with guppy. Specifically, it can be analyzed from the following aspects:
1. Size: Traffic light fish and guppy are similar in size, about 3-4 cm. So if they are mixed together, even if there is a dispute or fight, it will not cause serious injury to one party.
2. Personality: Both of them are relatively gentle fish. If they are mixed, they will not fight unless they are fighting for food.
3. Living environment: The favorite temperature of the lantern fish is 20-26 degrees, and the PH value is 5.0-7.0. Guppies prefer a temperature of 22-24 degrees and a pH of 7.0-7.5. And the guppy has a very strong ability to adapt to the environment, so the mixed culture of the two can focus on taking care of the red and green light fish.
4. Feeding: The feeding habits of the lantern fish are miscellaneous, and they prefer to eat water fleas, red worms, etc., but the general food can be eaten. The guppy is carnivorous, and it also likes zooplankton or bread crumbs. Therefore, it is more convenient to feed the two in mixed culture.
Red and green light fish can not be mixed with arowana, because arowana is larger and has a strong sense of territory, so it is only suitable for separate breeding. If they are mixed together, there is a great possibility that the lantern fish will be eaten.
