As a result of the length Bichirs expand as well as their have to breathe air, it is essential they are housed in long storage tank fish tanks that are not unfathomable, perhaps also an aquarium table. Aim for a fish tank that goes to the very least three times the adult size of the Bichir you have or plan to buy.

Pick aquarium aquariums that disappear compared to eighteen inches deep and also do not fill totally with water. This is very important as Bichirs have to be able to breathe from the air and also for that reason need to be able to swim swiftly to the surface area and also back to the bottom where they stay.

Ideally, these fish needs to be preserved at the higher end of the tropical temperature level array, around 25-28oC (77-82oF). Relatively soft to somewhat difficult water, with a pH around neutral or somewhat acidic is most likely perfect, yet water chemistry is not important, as long as the water quality is kept with regular water changes.

The occurrence of 2 types of Polypterus in Lake Tanganyika (P. ornatipinnis and P. endlicheri congicus) suggests fairly various water chemistries can be adjusted to.

These fish are thought about durable and really forgiving both of poorer water top quality as well as reduced temperatures, but it is not smart to examine these restrictions in the aquarium!

Illumination is not overly essential unless you choose real-time plants. Being generally nocturnal, the fish are likely to like dim lighting, although juveniles in particular do not seem bothered by brighter light at feeding time.

It may be worth fitting the storage tank with among the blue ‘moonlight’ fluorescent light bulbs for a hr or two of evening watching.

Making use of a timer, this can be set to come on right before the main light goes off, to provide an extra natural transition to twilight. Enhanced task is likely to be observed when the container is dimly lit, such as from history light in the area.

Success is more probable in soft, somewhat acidic water. Changes in the temperature level and chemistry of the water are likely to be part of the trick to generating spawning.

The male cups his rectal and also back fins around the female’s genital location to obtain eggs for fertilisation, after which the glue eggs are spread. Fine-leaved plants (or generating sponges) need to be attended to this.

Siamese Tigerfish, Angelfish, large Barbs, Cichlids and Knifefish are possible container companions. It has been observed that suckermouth Catfish tend to draw on the skin of Bichirs which aggravates them therefore it is not encouraged to maintain both sorts of bottom-dwelling fish.

Likewise stay clear of matching them with overly hostile types. In a very large fish tank it will certainly be feasible to keep a number of Bichirs with each other, supplied they are around the same size. They ought to generally tolerate each other, besides fighting over the food!
