When a livebearer female is close to giving birth she often hides because she doesn't want other fish around to eat her fry. This could also be a symptom of a disease. It's impossible to know without more detail or a list of the individual fish's symptoms.
You can keep a female and male hamster together, but you must consider where you would home the babies if she has them.
My sentence-making skills are currently inactive. It is safer to climb an inactive volcano. Your insurance policy is inactive.
caffeine, low food intake, lack of sleep, or inactive tissue due to obesity.
Its itchy.
no it would fight till death because betta fish are aggressive
If the fish are mature and in breeding condition they should mate within an hour or so and he will continue to drive her and mate with her on and off for as long as they are together. I would just leave them alone and let them get on with it.
Lack of activity would be a good thing when it refers to something that is harmful when it is active. So, for example, you have a tumor, but it is inactive.
I think that fish would be a platy (pla-eye).
No, the female monkey would NOT let the male...you know it would kill him :/
Provided you have sufficient space/water to house another fish. (A Platy needs around 2 gallons at least.) another of the same species or of a peacefull species like Rasbora, Danio, Tetra, Barb, etc will be OK.
Genetics
I put sharky in timeout. I moved him back to his small aquarium, he is pist. Did not think the Platy would make it through the night. I am thinking of getting different color platies. Then re-introducing sharky later and see how it goes. Appreciate any help if anyone knows how to calm down an aggressive betta? Had him for a year.
