Getting bettas to spawn can be tricky, and you have to be very careful or you could end up with a dead betta. What you need is a 10 gallon fish tank, and a cheap air driven sponge filter. You don't want any substrate because if you do have it you will lose lots of eggs. Provide plenty of caves for the female to hide from the male. To start the breeding put the male betta in the tank and put the female in a plastic breeder designed for live-bearers. This way they can get used to each other and get ready for mating. The female must be a little bit smaller than the male so he can wrap around her to squeeze out the eggs. But she can't be too small or he will kill her. So leave the female in the breeder and let the male build his bubble nest. It usually takes a week or so for them to get ready. When the male has a nice big bubble nest, and the female is fat and full of eggs and showing the operculum, let her go and let them do their magic. When they are done remove the female and put her in a tank by herself with very little current so she can recover. The male will tend to the eggs, remove him 2-3 days after the eggs hatch. Feed the fry baby brine shrimp or boil an eggs and make a paste by smashing the yolk and mixing it with water. And get lots of cups ready for the males, as they will begin to fight as they get older. Good luck!

The scorpionfish are a family (Scorpaenidae) of mostly marine fish that includes many of the world's most venomous species. The family is a large one, with hundreds of members. They are widespread in tropical and temperate seas, but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus Scorpaenichthys, which belong to a separate, though related family, Cottidae. Some types, such as the lionfish, are attractive as well as dangerous, and highly desired for aquaria. General characteristics of family members include a compressed body, ridges and/or spines on the head, one or two spines on the operculum, and three to five spines on the preopercle. The dorsal fin will have 11 to 17 spines, often long and separated from each other, and the pectoral fins will be well-developed, with 11 to 25 rays. The spines of the dorsal, anal, and pelvic fins all have venom glands at their bases. Most species are bottom-dwellers that feed on crustaceans and smaller fish, in some cases using the spines to paralyze their victims before gulping them. Others, such as the stonefish, wait in disguise for prey to pass them by before swallowing. Scorpaenid systematics are complicated and unsettled. Fishes of the World recognizes 10 subfamilies with a total of 388 species, while (as of 2006) FishBase follows Eschmeyer and has 3 subfamilies, 25 genera, and 200 species, some of the species being removed to family Sebastidae which other authorities do not follow. In addition to the two basic names above, common names for family members also include "firefish", "turkeyfish", "barbfish", and "stingfish", usually with adjectives added.

The Southern Blue Devil can be recognised by its colouration. It is greyish to blue or black with numerous small brilliant blue spots on the head and body. The anterior margin of the pelvic fins and the distal margins of the dorsal, anal and caudal fins are bright blue. Large adults sometimes have a blue ring low on the operculum. Juveniles have dark regions posteriorly on the dorsal, anal and caudal fins. It grows to about 36 cm in length. The Southern Blue Devil is a benthic species that lives in temperate inshore waters, usually on rocky reefs. The species is endemic to Australia, occurring from the central coast of Victoria to south-western Western Australia. It has also been called the Western Blue Devil.
