All other params are good Nitrites and amonia zero ph is 7 I feed tailapia beef heart blood worms and hikari gold but my 4in Oscar is still getting what looks like hith

Can someone help
 
i dont know if nitrates alone will cause hith but i know any nitrates over 20 can hurt your fish in the long run. i would do water changes more frequently that would also help. hopefully knifegill will see your post and be able to help you. hes awesome being all full of knowledge and what not. sorry im not more help.
 
40ppm is definitely part of the root cause (and the fact that they are genetically predisposed to HITH, IME).

The best thing for HITH is water changes and to not overfeed, spoiling the water. Do 50-75% weekly(depending on tank & fish size) and it will more than likely stop, but the scars from it never go away.

What size tank & how big is the oscar? If hes over 5 inches and in anything less than a 75, Id either feed every other day or do 50% changes every 4 days.

good luck
 
Stop feeding beefheart, see if that helps. I doubt 40ppm would cause it but definitely work on getting that level down with some WCs.
 
If your nitrates are as high as 40ppm, you really need to do a water change (you should try and keep them under 20ppm). Water changes are the only way to bring nitrates down. I don't think that the high nitrates will cause HITH unless your fish has been kept in those conditions for a long period of time.

agree with most of what you said, but W/C are not "the only way to bring nitrates down" . . . also, some people have moderate levels of nitrates in their tap water, which make w/c less effective than they might otherwise be

plants are a useful weapon in the fight against nitrates, although often a problem with Oscars . . .

there are also nitrate removal products and filters, which I am not advocating, but they are out there
 
It doesn't matter if your fish gets HITH or not its the fact that he needs good water. I hope you care about his health and just don't want him to be "ugly" with holes in his head and otherwise don't care about water quality. Anything over 20ppm should be fixed in a hurry. You should have a stable feeding schedule and routine that keeps 15ppm at all times from the first week of owning the fish.

Good luck!

I feel kinda silly now I totally forgot about plants, and I guess I meant to say the only natural way to get rid of nitrates. Like yourself I don't advocate the usage of chemicals when it comes to water chemistry.

Ok, well thats a lot of waste (high nitrates) for a 100g, unless youre doing 50% water changes every few days.

Heres what Id do:

Id get rid of 4 or 5 of the bichirs (or at least 4-5 of your least favorite fish) and have a strict water change regiment once a week of about 60% and feed them only what they can eat in about 30 seconds.

If you dont want to do that and want to keep everything you have in the tank and still have lower nitrates to help get rid of the HITH, youre going to need to do 50% changes about every 3 days AND change their diet to a good pellet, IMO....which is a lot of work for a tank. Either that or get a 55 gallon sump for the tank and do 50-75% weekly.

Now, my advice is coming from an aspect of not overstocking, which isnt the route youve gone. I dont like to overstock and I dont like to do water changes, so Ive got the minimal stock, even in my 265g with a 48g sump. Even with what I have, I still maintain 50% changes weekly.

Good Luck with whatever you choose.
