Guppys tail getting ragedy.

my new female guppy's tail is getting ragedy and is staring to split abit, it could have been the filter, so i changed it. do you think that the male is harrasing her too much?

male guppies are pretty bad when it comes to chasing the females. They will constantly pester them and can cause physical damage. But it also depends on what else is in the tank. If there are barbs or gouramis or even certain tetras, they will all have a go at guppy tails.

Poor water quality can lead to tail damage and bacteria can get into the damaged area causing fin rot. Bacterial infections usually show up as a red area. Poor water quality often shows up on the fish as cloudy eyes.
If there is no infection then the tail should heal up in a week or two without any help from you.

If you notice the male continues to pester her you might want to isolate him in a breeding net. They sit inside the tank and are nromally used for pregnant females, but can also be used to contain a randy male

thanks but she died this morning dont know why......

sorry to hear she died
She might have picked up a bacterial infection and when fish get sick they go down hill really quickly.

Did you quarantine her before you added her to the tank? It's quite a good idea having a spare container to hold new fish for a week or two. This gives you a chance to monitor them for disease and if something does happen, (they get sick) you can treat them in the quarantine tank instead of having the disease get into the main tank.
A simple quarantine tank can be made from a 40litre plastic storage crate or a small aquarium. Have a plastic box filter full of Ammogon or Zeolite. This stuff absorbs ammonia and helps keep the water clean when the fish are in there. It can be recharged is salt water after use, then dried and packed away for next time.
Just set the quarantine tank up the day before you get the fish and leave them in it for a week or two. If there are no problems then you can move them into the main tank.
The other advantage of having a quarantine container is if a fish does get damaged you can isolate them and give them a chance to recover away from the other fishes.

Yeah Guppies aren't a really hardy fish, especially in a community tank. I've never had a single Zebra Danio die on me. Sorry about the loss
