No, I put my plocostomus in with my male Betta fish, even though she was bigger, he killed in an hour.
======================================================
Yes, but keep in mind they have different water requirements.
If a pleco dies when kept with a betta it's more likely to be due to tanks size and water quality issues rather than the betta killing it.
Bettas are top dwelling fish, while plecos are bottom dwellers. Unless in a small container there won't generally be much interaction.
Yes
yes betta fish have to live alone or one will kill the other.
Any.
Yes it can
No. Male Bettas will not tolerate another Betta in its vicinity.
A Plecostomus can live by itself.
This is the LAST thing you want to do! Putting a male betta fish in with another male is horrible because male bettas will fight to the death...not good!
Male betta's are more colorful then female's
From a female Betta. Then the male Betta fertilizes them when they breed together.
A male betta can live 3 to 5 years when cared for properly. This may seem less when you own the fish, but this is due to the fact that male bettas are usually a year old when you buy them in a store because they are not sold from breeders until their fins fully develop
The male will kill the female after he spawns her. If she won't spawn he will still kill her. No male Betta will allow another Betta (male or female) to live in its vicinity. So the answer is NO.
