Hi I'm wondering why my guppy is missing part of his tail, and part of his top fin is hanging, it can't be fin rot because I got him yesterday and he was fine, he wasn't sick, I think it was my Betta because he was chasing him for a bit and my molly was okay with the guppy, my algae eater is small so he couldn't do that damage. I'm only 11 so I can't just go to Petsmart and exchange it, I have to ask my parents to go, and this happened overnight so and I can go to Petsmart tomorrow and I don't want my Betta attacking it again. It looks like one more good hit will finish him. My tank is a heated ten gallon, the other fish in there are a black molly, a Betta and a golden algae eater. My water parameters aren't perfect because I have just finished cycling, my nitrates are about 20 ppm and nitrites are about .2 ppm I'm doing partial water water changes to change that.

Bettas and guppies don't mix. Because guppies have bright colors and large fins like bettas do the bettas see guppies as a threat. Also, guppies and Mollies are schooling fish which means they need to be in groups of 3 at the very minimum.

I'm going to get more guppies but this was to see if it would work and my molly there's only one because it's aggressive towards other mollies, and can i swap a female Betta with a male because I've heard females aren't aggressive

It really depends on the betta. Some males do great with tank mates and others don't. Same goes with the females.

I'll try a female though, I'll get a small one. I can give the Betta to a friend.
