O_ROD created the topic: What's wrong with my Oscar?

I noticed today that my one Oscar has white spots on his sides. He has one near his gill and 2 smaller, lighter ones on his other side. I feed a constant diet of frozen bloodworms that haven't been refrozen. He's in the tank with another smaller oscar and a leopard pleco. Is he getting picked on or is this some sort of sickness?

Thanks for your help.

First of all, it would be very helpful if you can provide us with your water readings. That would be ammonia, nitrite, nitrates and pH. Okay, these white spots, do they look like grains of salt by any chance, or are they bigger? If they are bigger, do they look like they are raised?

What size tank are you keeping your Oscar in? Sorry for the questions, without knowing a little about how you are keeping your Oscar, it is virtually impossible to say what is going on with your Oscar. Finally, a photograph is worth a thousand words

It's only a 30 gallon tank as the fish are just juvies, I'm trying to find an affordable new home for them.Don't have any water testing supplies as of yet either :(

They don't look raised, and he's been aggressive with the other oscar, just abrasions maybe?

I have altered the photos so we can actually see them. Don't worry, I know it's not your fault.

That does rather look like some kind of fungal infection. Doesn't look like something actually growing on the skin? Are there any scales missing. The flesh directly under the skin can be very white, especially on dark fish like Tiger Oscars. If it is indeed a fungal infection, You could try something like pimafix, this can treat external fungal infections.

However, it is always a good idea to know what the water is doing. It's rather like going to the doctors for a checkup. He can take blood etc and sometimes find out any underlying problems. This is testing the water is quite important, if it's bad, that can often account for fish illness. If you don't know what the water is doing, it is very difficult to diagnose things

Tomorrow I'll be picking up some more food so I'll grab a water test kit. The oscar actually looks very healthy apart from the white spots. after looking closer, they almost look like he's missing scales, not a growth.

I also have a lead on a second hand 70 gallon tank, pretty excited :)

It is extremely common for Oscars to receive cuts/abrasions/wounds, especially if you've got more than one. Believe me, some of my Oscars have had really nasty looking injuries. I actually don't do anything, I let nature take its course and I've never had a problem. Now, if these wounds on your Oscars haven't shown an improvement within at least three days, I think you should look a little closer. If the water is in good condition, even nasty wounds should heal up reasonably quickly on Oscars.

Good one on the water test kits, they are absolutely vital. 70 gallon tank, excellent! Look forward to seeing some photos

My little Oshie gets little nicks on him all the time. Just from moving to quickly near a decoration or bumping into things. It heals usually the next two days. It sort of looks like what my oscar gets, so hopefully it will clear up soon. :)

Your oscars diet is frozen bloodworms. This will cost you a fortune when they get older and bigger. Also oscars should really be fed a varied diet. I feed mine maggots, worms, cichlid pellets, pond fish pellets and prawns. Im sure others will have other suggestions
