I bought a two very small true percula clown fish and one is beating up on the other one!! and now they both look like they have ich ive been treating the tank for a couple days now and they still are eating but what can i do to stop the fighting or is this normal??
Feed garlic soaked food. What ar you treating with? Copper? Do you have corals? What size tank? What are its tank mates? How old are the fish? How long has your tank been up? How much lr/cover is in your tank? When did you add them? Where did you get them?
I think the behavior is somewhat normal. I have had the same thing going on with the two young picasso clownfish I purchased right before the first of the year. I believe it is one establishing dominance over the other....at least in my case, the more agressive one keeps the other corralled in the corner near the overflow. In doing so, it is able to eat more food and expend less energy. In the 3 months I have had the fish, the more dominant is at least twice the size of the other now. I have noticed the beatings seem to be letting up...and expect eventually they will be boyfriend and girlfriend.
With that said, I'm sure in the fight for dominance clownfish can be killed by the other or weakened to where disease can set in. You might consider isolating one of them in a specimen container for awhile. I use those breeder nets and hook them on to the inside of the tank to isolate fish. I would say be careful treating them unless you are sure there is a parasite...a lot of treatments can be hard on the fish.
I also agree with feeding garlic soaked foods and maintaining a high quality food during this phase to help maintain their health.
I'm using ich attack in the tank right now and feeding frozen brine and mysis I have to go pick up some garlic! I currently have the one aggressor in quarantine in a strainer in the tank. The other clown has quite a few more spots than yesterday but is swimming threw the anemone and eating fine!
