Urgent help with RTC

  • We are currently upgrading MFK. thanks! -neo
Such coincidences are rare: if all had been dandy and you added an antibiotic and at the same time or soon the problems began, then it has something to do with that - either with the med or with the reason for medicating in the first place. What decease are you treating and what fish are you treating? Are there tank mates? If yes, what's their behavior like?

A photo may help tremendously too.

Never had any problems before starting this treatment, I was treating my arowana because it had damaged its head and eye I assume by jumping and hitting the lid and I just wanted to make sure the injury did not turn into an infection or cloudy eye so it was mainly a precaution that I now regret :( and the other fish in the tank arn't aggressive, I have never seen damage or aggression since I have owned them. Here some pics, I will try and get better ones tomorrow.

Yeah, hard pics. I see what you are saying about the weak barbels and I can see no huge problems, like hemorrages, erosions, big inflammations, etc. but I cannot see the slight redness you refer to.

I hope you used a small or prophylactic dosage, as such dosages should not normally affect the biofilter. Without knowing more details, I'd say I would not use such a strong antibiotic. I'd use, if any at all, something like Melafix - a mild anticeptic (or a bit of salt). Some keepers report Melafix helps with cloudy eyes too (a potential benefit to you because your aro does not have it at the moment) - I admit I have no clue why Melafix would help the eye problems but several reports I've read on here cannot be denied, at least at their face value.

No, I didn't mean the tank mate aggression. I meant as your RTC was going through all those alarming symptoms, what his tank mates' behaviour was like? Normal or highy stressed too? Obviously if it was ammonia or any other water parameter far out of whack, as suggested above, all fish would be very uncomfortable and stressed in some way.

If they were not at all, then this points away from your water parameters and away from kicking-back your bio-filter and points to a bad reaction your RTC had to the med.

Yea sorry they are dark, I had already turned the light off and didn't want to stress him. The redness and the barbels was the only symptoms and the redness has faded slightly so in hoping thats a good sign he is improving.

No, I stupidly used the prescribed dose on the bottle :( but thanks for the tip about melafix, that sounds like the way to go in the future.

Oh rite, no all of the other fish are completely normal, even the arowana has healed up almost completely, the only thing that is worrying me now is the high nitrate reading I got today, do you think this could have been caused by him shedding his slime coat? Or bacterial reaction to the meds?

If all other fish have been normal throughtout this ordeal with the RTC, then the bad water hypothesis can be discarded.

Shedding slime would not affect water tests, not at all in a properly run tank anyway.

If all your nitrate readings had been ok untli that last one, then the last one is most likely a fluke...

...(unless something unpredictabe happened, like your water source changed to now include lots of nitrates; or you have a contamination of your water with a fertilizer containing a form of nitrate; etc.)...

I'd measure again and measure your tap water too at the same time and same conditions and, if still confused,I'd take it to my LFS who usually measure water for free to see if my kit has gone bad (which with the expiry date of 2017 cannot be..., unless you forgot to close the bottle for a long time - it coud spoil then).

Also, it could be that some meds interfere with certain tests. So, again, if still confused after all of the above is done, I'd take out the med with water changes (I dont use carbon but you can use that to take out the med too) and take your measurements again.

I assume you use a nice liquid test like an API Master Kit, not strips - strips are no good.
 
He is looking much better today, redness has gone and he is acting more normal :) just the limp whiskers to fix now but I would imagine that takes a lot of time. Yes I use the API masters kit for testing, I will post the results later. Thanks for your help :)

Great. With the water chngws you did, redness is gone, whiskers will fix themselves
 
Both tests since the high nitrates have been perfect and the red tail looks so much better :D he lost part of his right whisker and the tip of the left 1 looks floppy but apart from that he seems back to normal, I'm so happy :) thanks for all of your help everyone I really appreciate it.

Great. I assume by "both tests" you mean nitrates in your tank and nitrates in your tap water.

So, to me, the tentative conclusion is that this might have been the case of RTC's strongly adverse reaction to myxazin (I hope you have not erred when calculating the dose).

It will be interesting to see if anyone else has pro or con data to that. Would you mind if I start a new thread with this question in the title and a link to your thread? Just would like to learn more. If you'd do it, that be even better.

I don't have much hope but one never knows unless they try...
