Bettas have a lot more personality than guppies, and require less space (5 gallon+). However, I have had boredom and tail biting issues with mine, so I had to upgrade to a 10 gallon tank with pygmy cories to stop him being bored. This is a risky move as many bettas are aggressive and won't accept tank mates.
Guppies require 10 gallon+ tanks, and are stunning creatures. However, they are less intelligent and have less personality than bettas.
Both fish require a heated and filtered tank, and no matter what you decide it is of upmost importance that you do a fishless cycle to create a healthy bacterial colony before you add any fish. Without doing this your fish will be in pain from ammonia and nitrite spikes and may die.
It depends
Bettas go great with Guppies but with males you are restricted cause you can only have one fighting fish AT ALL with females you can have as many as you like
no because the betta will fight, hurt or maybe even kill the guppie
Guppy or a minnow or a betta
No.
No. Male bettas can be kept in community aquariums, but should not be kept with fish that look anything like they do, or are small enough to eat. A male betta will mistake a guppy for another betta and kill it. Female bettas, however, can be kept with other "betta-like" fish without a problem.
Fish are not stupid. There is no chance that a Betta splendens would mistake a guppy for another Betta.
You can try to put Guppy fish in with your Betta fish. That would be one of the only fish that i would put in with my Betta fish. I say that because i have a Betta male and he is OKAY with guppies. the first guppy i put in his died to to getting picked on by him but the others did not, so just give him another chance if you decide to get guppies. Hope i helped!
why would you want to kill a betta D:
yes betta fish have to live alone or one will kill the other.
yes
The Betta fish want to kill eachother. That's what all Betta fish want to do, that's a natural thing.
Betta fish are very aggressive. They pick at their scales and then they're gone!
No.
