Hikari Usa AHK73254 Prazipro for Aquarium, 4-Ounce

This stuff is a miracle in a bottle!I had a tentative diagnosis for my fish after talking with AI about his symptoms: flashing, sitting on the bottom of the tank, loss of color, fast breathing... AI said likely gill flukes.My fish sat on the bottom of his tank for 2 days, barely alive, while this stuff was being shipped. I was sure he was going to die. I thought he for sure was too far gone.This arrived, I dosed my tank. I'm not exaggerating at all- within FIVE minutes of dosing, this fish that was previously half dead, gray, sitting on the bottom of the tank was swimming... for the first time in 2 days! Now, 40 minutes later, he's swimming better and more normally and only taking small rest breaks. Yes, my fish is still gray and still visibly ill (it's been 40 minutes, of course he is!) but, for the first time in days I finally have hope for him. I was surprised how fast this brought relief. Fingers crossed that he continues to improve and regain color and strength. I can not recommend this product enough. Every goldfish owner should have this on hand!

I have a 4 yr old female black convict cichlid that started hiding in corner, staying on the bottom and not swimming around except to eat a small amt. She wasn't feisty and interacting with us, so I started looking for something to try because I thought I was going to lose her. I saw this and it sounded easy to dose, well let me tell you, it's worth EVERY cent! Our girl started coming out a little more everyday and it's been about 4 days and she is interacting with us again and swimming around! I will be doing the regular water changes tomorrow and I will dose her again just to make sure everything is taken care of. I figured she was worth trying to find something to help her and this product did not disappoint!

Absolutely one of the best meds out there for sick but med-sensitive fish. I keep this and paragaurd on hand at all times

Works wonderfully, but caused my tank to smell like burning rubber. I could not figure out at first wth my tank smelled so freaking bad but finally figured out it was this stuff. It also built up like a slimy, stinky sludge in my prefilter. I am not sure if it's from the medication coming into contact with a heater or what, but you'll want to clean your filter and have some activated carbon ready to deodorize your water once treatment is done.

It works as advertised

This stuff is amazing! And just in case you don't want to read my whole review... if you just bought a puffer of any sort --especially those Walmart Green Spotted Puffers... GET THIS and follow the instructions exactly--even if they don't look "sick". Your results will be worth the price. Puffers do not breed in captivity and get internal parasites in the wild. This will get rid of that with ease and make the likeihood of reaching adulthood greater. I have 3 tanks with puffers and they all got treated first thing when I purchased them, and is perfect for your med tank. My most glorious result is my Fahaka Puffer. We recently bought this emaciated guy who was like a stick--or rather, more like a tad pole, huge head, no body weight. He didn't have any use of his caudal/anal fins and kind of just shook side to side to get around and mostly stayed on the bottom. 3 weeks with PraziPro every 3-6 days and he has gained a lot of weight, uses his fins and doesn't look like an old man anymore. He's put on at least 50% more weight with a balanced diet. My GSP also got prazi and is as big as I've ever seen a Walmart puffer get. Everyone says they die right away, but if you TREAT THEIR PARASITES and keep good water conditions (marine brackish), he will thrive. Lastly, my little dwarf puffer, he got this too. He's a riot to watch chase the blood worms and ghost shrimp, he used to sit at the bottom also, but now picks on a rams horn double his size. Get this, get this, EVEN IF THEY DON'T LOOK SICK. A lot of puffers can host parasites without looking ill until it is too late. Save yourself the pain and get rid of them immediately!

I want to start by first saying the negative reviews for this product are complete crap. First, mine was clear when I got it... not pink. My fish were showing signs of flukes. Their behavior changed and even their coloration was off. My yellow tang was almost white and my trigger stay lodged in the rocks.. if he did come out he would dart around the tank... almost in a panic state. I followed the instructions... water change followed by skimmer off and any carbon out of the sump. I made sure my measurements were exactly as the bottle recommended. It took 3 of my measuring cups to treat the tank.. I have a powerhead on each side, so one dose on each side and the final in the sump. I kept the lights off and let it go. It's been one day and I can tell you that the fish are 100% acting normal. Their color is back, no more rubbing on the sand or head shaking. My coral is doing just fine. All crabs and shrimp are fine. I will probably wait another couple days then change the water and turn on the skimmer. If you've used this product and things in your tank are dying I am sorry to hear that. Either your fish were sick beyond saving or something went wrong. I can speak from my experience... worked for sure.. perhaps consider buying from BRS if you worry about a bad batch from amazon.

Works fast. Saved fish
