Plz help, what's wrong with my guppy?

zeezMOG said:

So more than 3 months ago I got 2 pregnant guppies and a synodontis catfish they all live in a 3.5 gallon tank which I know is small, but they all were living happily and they both gave birth and everything was good they were like the three musketeers, except for when I fed them the large guppy, its just a bit larger, would chase the smaller one with out nipping it, but today I saw the smaller guppy's side fins ripped to the half and a little on the back fin, and the larger guppy did it because I could still se it chasing it and nipping it, it definitely wasn't the syno. Why did she suddenly got mad? Thanks

It could be territorial disputes. Since the tank is so small, it is really only suitable for shrimp. Guppy's need an 10 gallon + and whatever synodontis species this is, needs a tank of 55 gallons even if it's the smaller species. Can I see a picture of the synodontis and the guppy?

Also, it could be that the larger one is trying to protect their babies.

I removed the fry about a month ago and the guppies were always friends and hanging around with each other, here are some picture.

Your tank needs lots of surface plants. This will separate them from each other.

I think the cat is a synodontis aterrimus but I'm not sure.

Either way he will get too big for the tank and the substrate isn't ideal.

I think he is a featherfin squeaker. He needs a 50 gallon minimum for fully grown and needs a lot of hiding places.
