Betta splendens can be hybridised with B. imbellis, B. mahachaiensis, and B. smaragdina, though with the latter, the fry tend to have low survival rates. In addition to these hybrids within the genus Betta, intergeneric hybridisation of Betta splendens and Macropodus opercularis, the paradise fish, has been reported. [43]
Male and female individuals of Betta imbellis can live together outside of breeding season, as well as getting together for breeding. Males will build a bubble nest before breeding. After mating, the male catches the falling eggs and places them in his bubble nest. In 1–2 days, the eggs hatch and continue to absorb their yolk sack for 2 days.
Many members are common aquarium fish; by far the most famous is the Siamese fighting fish, Betta splendens (note that the domesticated form is very likely a hybrid). Most (not all) of the 70+ betta species are paternal mouthbrooders; the remaining members of the subfamily are bubblenesters like most osphronemids.
All Betta species are small fishes, but they vary considerably in size, ranging from under 2.5 cm (1 in) total length in B. chanoides to 14 cm (5.5 in) in the Akar betta (B. akarensis). [1] Bettas are anabantoids, which means they can breathe atmospheric air using a unique organ called the labyrinth.
Betta mahachaiensis is a species of bubble-nesting betta native to Thailand, [2] where it occurs naturally near the Gulf of Thailand. It is typically seen in stagnant waters in swamps, pools, and ponds. The species can be found in brackish waters, with salinity levels between 1.1 and 10.6 parts per thousand.
In 1992 Egypt bought 221 M88A1 recovery vehicles for its M1A1 tanks, then in 1997 Egypt bought further 24 M88A2 but also obtaining the right for domestic manufacture. 50 M88A2 units were produced in the first batch, with further 13 produced in the second batch in 2002.
