Guppys fins freying?

[momo3681]

Y male guppys back tail fin is freying? Why is it doing that?

 

[Fishkeeper26]

It could be because of a few things. What are your water parameters? What size tank? What all is in the tank?

Well, I am cycling my tank with these fish, 10 gallon tank, a snail and 1 black Molly

What are your water parameters? It shouldn't be nipping, but the Mollie will need a bigger tank

 

[momo3681]

I have not got a testing kit yet. But, the Molly should b fine if I only have one right?

 

[Fishkeeper26]

Theyre still too big for a 10

Ok, well back to the guppy...what's wrong?
