One of my Platy fish is acting weird

[carlfishlover]

I have a fish tank with 4 platys and they are all acting fine except one. This one platy is isolated a little from the group and at the surface. I saw him blowing bubbles and I read online that this may be a sign of lack of oxygen. This tank has a Top Fin Silentstream 10 Power Filter with cartridge and the flow current of the water was put on low so I bumped it up a little to see if that would help. I don't know if I should place the current higher because I don't want it to be too much or for it to bother the fish. This is a planted tank and sometimes when the other platy fish swim by him he does kind of bite at them. The 3 other platy are always swimming together and get along fine and arent always at the surface. I changed the water less than a week ago and it's very clear. What should I do or is this normal behavior or will it resolve on its own?

Hmm. Does he have full color like the others? (No discoloration?) He may still be trying to get acquainted with the tank and is nervous/stressed. How long have your platys been in your tank?

I don't believe his color has changed but him and two other ones are all slightly different shades of orange. They have all been in the tank for about 9 days.

Your bio states that you do not understand the nitrogen cycle.

Its really important that you learn about this.

Did you cycle your tank before you added the fish?

Hmm. He may still be settling in. I take it he is a fin nipper. He sounds a little stressed.

I had other fish in the tank before this who died of an ick outbreak however most of the water was changed after that and treated with API Super Ick Cure and Top Fin Readistart Nitrifying bacteria starter is added in there after every water change along with the water conditioner. I did the Ick cure treatment on them as soon as I got them so I don't think it is ick and the Top Fin Readistart Nitrifying Bacteria Starter says it allows immediate introduction of fish so would this mean that the tank is cycled?
