I have a pair of day geckos. however, I saw a female day gecko with the tip of her tail ripped off. I saw aggression in the male day gecko where he bites the female. my cage is big enough to keep these two. but I intend to separate them for now until she heals back. but I saw some info that male day gecko might be aggressive towards mating. so any additional info on why he keeps doing that? should i separate them forever and put them together only for mating? any experts on their behaviors?
