if you can live with the smell
Of course it is... are you going to eat your fish alive then?
i dont know maybe
This depends on where the water from the toilet goes. If your toilet goes into city sewerage which is treated, then it's probably safe (as long as the fish isn't big enough to block your toilet!) Any other toilet system should probably not have dead fish in it, because any diseases or parasites that the fish are carrying (sometimes without symptoms) could get into a local waterway and have a devastating effect on native fish.
Yes it's perfectly safe. They just eat the dead skin and that is no harm.
Dead fish.
the male fish will protect the female if there are other fish. just make sure when your guppies have hatched, they are safe in a other tank.
if they are dead they go down the loo but if they aren't dead and have gone missing check the loo any way just to be on the safe side
They send them out for repair and leave the other instruments in a safe place.
Yes, but it should be when it's nearly dead, not when it's full or kind of full.
No. They will kill each other.
Panga is a white fish that has been deemed safe for consumption.
For a freshwater tank, its safe to add fish after the the ammonia, nitrite, and nitrate levels are safe for fish. Ammonia and nitrite should be at 0 ppm and nitrate levels should be very low, under 50 ppm. You should also make sure that other parameters are safe for the species of fish that will be living in the tank.
