Aquarium for cockerels
Cockerel is a fighting fish, very popular among keeper because of its unusual color and interesting behavior. Typically, beginners tend to listen to the seller - and the seller often says that this fish needs a small aquarium, it is not necessary to heat the water, and in general the cockerel is extremely unpretentious in maintenance. However, there is quite a bit of truth in these words, and the cockerel deserves a completely different departure.
The Siamese cockerel comes from Southeast Asia - that is, it is a typical tropical resident. It belongs to the so-called labyrinth fish, which means that it can breathe atmospheric (not dissolved in water) oxygen. This makes the cockerel suitable for beginners as an inhabitant of the terrarium - it really does not need large volumes of water and any specific food. These fish are omnivorous and eat any food - frozen, live, artificial. But keeping a cock is better alone - they tend to fight not only with each other, but also with other fish. Even for males, the water temperature is critical - they definitely need heating, the water should not be colder than 24 degrees.
In general, the choice of an aquarium for a cockerel is not so complicated. You should immediately exclude the round options. First of all, it is difficult to care for them, even cleaning algae from the glass can be a big problem. In addition, recent studies in aquarium studies say that round aquariums have a very bad effect on the health of the fish living in them.
An ideal option for keeping one cockerel is a classic rectangular aquarium of 20 liters. It is easy to maintain the right temperature and balance in it; it is quite simple to decorate it and make it a jewel of the collection. And a cockerel in such a volume will be very comfortable. Among the shortcomings - many believe that such an aquarium looks very boring.
If there is not enough space, then you can also choose a rectangular aquarium, but 10 liters is the minimum volume in which the cockerel will feel good. In smaller volumes, it is very difficult to monitor the desired temperature and balance. And the fish there is unlikely to be healthy.
In the case when it is planned to keep the cockerel not alone, but with a female or with other fish, you need an even larger volume of the aquarium - from 40 liters. In addition, shelters for the female or algae will be needed so that other fish can hide in case of cockerel aggression.
Aquarium with a cockerel does not need aeration, as well as backlighting. But the filter does not hurt, especially with a small aquarium. And you also need a lid - because a cockerel can jump out of the water.
