They would not fight anyway. Male Bettas will only fight with male Bettas. The Convict Cichlid is a much larger fish than the Betta and has a much larger mouth in proportion too than the Betta so I would assume that if they were to fight the Betta would not stand a chance.
Crowntail, Veitail, and Halfmoons.
Yes they will.
Male crowntail bettas have the large finns commonly associated with the betta fish with a small difference in the edges of the tail. Females have very very short fins with the crowntail edges
convict cichlids are the most aggressive cichlid there is it will fight with all fish convicts an green terror cichlids are the most aggressive cichlids so i would suggest that you not do that if you are about both fish
It is quite possible that the Convict cichlid would kill a fish as small and slow as a Betta. I would not try to mix other peaceful species with large aggressive fish like Convicts.
A crowntail is a beta fish with a teardrop-shaped fan tail. The tail of a crowntail beta distinguishes it from other betas. The crowntail is a Siamese fighting fish that grows to 1.5-inches in length.
Win what? be more specific. If you mean in a territorial dispute, an adult fighting fish will get eaten (literally) by and adult convict cichlid. but if the cichlid and the fighting fish are of the same size then the fighting fish would be at an advantage.
No. They need very different water parameters.
no. Bettas are to be kept separate, unless they're all female and you give them plenty of territorial space. Beta+ other beta= fight/death/severely injured sick fish
yes
Bigger fish
