I dont know, i have 2 silver dollars at least 4 yrs old and when i was cleaning the tank they started doing it. I plan on watching them for the month and see if we have babies. I don't go by all the rules everyone says. For 8 yrs I have had gold fish with tropical fish and I am told they won't live because of different temps, NOT TRUE. I keep the heat off in the summer, even thou my house is air conditioned at 62 in summer. Its by a window, no drafts and no i don't get a lot of algae either. When I clean the tank i put really warm water back in, if you weren't told keeps ick and stress down when you do that, helps fish to heal quicker. I feed them every 3 to 4 days, less ammonia, cleaner tank, less water changes. I have well water, direct from tap. When testing perfect every time. Maybe it was the warm water I added that got them in the mood, try it.
All animals can reproduce. Bettas are no exception. When a male and female are left together under the right conditions, they will spawn.
Get single player commands then type in spawn silver fish. Make sure it's not on peaceful.
The answer is spawn
fish that can spawn up to 100,000 eggs each spawn
Salmon is one fish that travels up a river to spawn.
spawn
Glofish are just Zebra Danios (Brachidanio rerio) that have been interfered with genetically. They will spawn whenever the water conditions are exactly correct for them and they are in breeding condition at the same time. I do not know if the fry from a glofish spawning would result in more glofish or revert back to the proper fish as nature made it.
diet consists mainly of fish spawn,crustaceans,and small fish
you have to be in creative at first
Fish and Aquariams
Goldfish spawn when conditions are right for them. (Usually Spring time). They do not get pregnant because their eggs are fertilised outside the body. They are egg scatterers.
Nothing. They should develop into fry without you doing anything. The fish would not normally spawn if the water and conditions are not suitable for the ova to develop.
