i found this about breeding frogfish if ur interested
Spawning and reproductive activity in frogfishes is fairly well documented and frequently observed. In fact, they appear to be one of the earliest species observed to reproduce in modern aquaria. Frogfishes are even commented upon in classical history by none other than Aristotle, 344 B.C.! Like so many other marine fishes, it is the rearing of their larvae that has been so elusive to aquarists. Oftentimes, these events in aquaria occur soon after the import of a gravid female. Unfortunately, fertilization of the eggs is external, and fruitless without a male of course! Dimorphism is not apparent in most species – the girls and boys generally look alike... to us humans at least. Reproductive females become quite swollen and egg-laden just prior to copulation (mere hours/days prior). Some frogfishes move to deeper waters to spawn, but overall they are regarded as relatively shallow water denizens of the reef. At least Histrio, the Sargassumfish, has been observed to spawn year around with no apparent season or reproductive cycle. Courtship occurs by day, although the spawning event itself may occur day or night. Males chase the gravid and clumsy females by "nudging" them along and above the seafloor just prior to a brisk dash by the pair to the surface for egg release and subsequent fertilization. Spawns are comprised of gelatinous rafts or ribbons that usually float. Both Antennarius and Histrio have been observed to spawn in aquariums. We have good reason to ultimately be hopeful of rearing frogfishes successfully in aquaria as the eggs are large and the planktonic stage for larvae in some can be fairly short (21 days, Thresher 1984), although the range in this family extends as far as 2 months or more. Although broadcast spawns are the rule in this group, some demersal strategies have been observed with the parental care of egg clusters upon the flanks of the adult frogfish. Its best to separate frogfishes in aquaria after a spawning event as males can become aggressive or belligerent. Frogfishes by nature are solitary animals.
