SAD DAY NEED HELP SAVING MY FEMALE MOTORO STING RAY

I'm no expert but I don't think melafix will alter your readings that badly...maybe I'm wrong but Ive used melafix before with no adverse readings. Looks like ammo burn to me...but pics blurry. I'd test your water again...do a good size water change...and think about getting those numbers in spec...that would be my guess as to why your rays are sick.

GH-general hardness
KH-carbonate hardness
PH-I guess the best way is to say the acidity or alkalinity of the water. Less than 7 is acidic, more than 7 is alkaline.

NO2-Nitrites (the bad stuff that should be reading ZERO at all times!)
NO3-Nitrates (Also bad but has to be at a higher level to truly affect the fish, you want to shoot for <=20ppm in your tanks usually)


NH3-ammonia and what I believe is your problem. That looks like ammonia burn to me on those rays. If thats the case your tank went through a crash and is recycling so your ammonia levels are high, thus causing those white fringes on the rays' disks.

My other theory is you did a big water change recently and have city water and didnt dechlorify it and those are chlorine burns.

Either thing is deadly to all fish, you need to move your rays to a stable tank asap.

Good luck

your water can look pristine and crystal clear and be a toxic waste dump to fish under the right conditions.

Invest in a liquid testing kit. The strip tests do not work accurately in any respect.

Be careful with super large water changes. Your rays are stressed as it is and changing the water chemistry that fast even in a helpful way can be deadly too.

SMALL water changes, 15-25% at a time, every day until this is sorted out.

Buy bottled bacteria to help the process along, it sounds like it doesnt work, but it does and it works fast.

Use Seachem Prime to help buffer some of the harmful chemicals in the water. Its primary function is to dechlorinate water, but in a serious situation like this it can be used to detoxify water for a short time...no gaurantees on this working but it may provide some relief to the rays.

Good luck, we all start somewhere in this hobby and make mistakes, it sucks when the mistakes cost us our prize fish but we pick up and learn and move on to being better monster keepers.

Mods please move to the ray section for better feedback

Looks like it could be bacterial. There are better meds for this

look at his water params...I'd put money on it being ammo burn...even if he isn't accurate with his numbers he is still registering ammonia and nitrites.

In the event vamptrev is correct because he most certainly knows far more than me about rays I would also look into some bacterial meds that are ok for rays (I don't know where to begin with that because I know theres a slim few you can use with them). Adding salt to the water (barring again the sensitivity issues with rays) may also help to aleviate some of the problem.
