Good product, bad delivery
My oscar fish got pretty beat up by another tankmate (which I got rid of after this). I did a couple salt dips after noticing a white outline on the edge of its fins. Its an albino so I couldn't tell if it was due to regrowth or infection. Either way the salt couldn't hurt. But the majority of the recovery was just using this. Seems to have worked well, some slow regrowth going now. He should make a full recovery. The bottle did arrive broken and it did spill inside the box. The lid snapped off. I don't think that was necessarily the companies fault as much as it was Amazon's. It took like half an hour going through menus just to get assistance. Absolutely ridiculous. But other than that it seems to have worked. Will continue dosing until it grows it back entirely. You can see the difference from the first day to now. First picture was on monday and the second was saturday. Not bad considering. It looks like it will be awhile before hes full go though. You can see his fins and tail were more frayed initially, but now they seem to be coming more together. I am doing frequent water changes now, to help it heal faster. I just redose for the amount I take out. I had a bottle of paraguard on standby seeing as I just started this tank, but I really should've have the stressguard instead. Will likely keep a bottle of this on hand now as well. EDIT: looking good. Pattern changed on it slightly since then, but its as happy as it was before the scuffle. Can hardly tell aside from a tiny bit missing off the top of the tail.

this saved my fish’s lives
first of all, I do not usually leave reviews.. but I just wanted to put this out here in case anyone else finds himself in a similar situation and aren’t sure what to do. I have very large South American cichlids in an outdoor pond and naturally sometimes they fight. Anytime I see anyone with any injuries I always dose the pond with this bc it’s safe for the other fish and the plants in there. It’s essentially harmless to use and can pretty much only help. I’ve used this probably dozen times for small injuries and never had any problems. This particular time was a true test of its efficacy. Two of my adult cichlids had the worst wounds I’ve seen in any of my tanks. A blood parrot was missing like a third of their jaw/face from locking jaws with someone and getting their face bitten, and a different fish had what looked like a stab mark (??) that was like almost a full inch long with some weird opaque white stuff coming out of it 😭 These 2 fish don’t bother each other at all so it may have been a coincidence idk but it was such a nightmare and I did not think either of them would come back from their wounds. I considered euthanizing them, but honestly, I didn’t have any way to actually euthanize fish that size.. so I ordered a couple bottles of this overnight and prayed for the best. It says it’s safe to double the dose so I did and within three days, the fishes face grew back almost perfectly and the other fish with the stab wound already had a visible closed scar. I was so impressed (and thrilled!!) It says it has colloids that bind to exposed proteins in wounds, and after my personal experience and consulting some experts online, I truly believe this product does what it says, and is worth every penny.

Worth it.
I have tetras, plecos and snails and no issues when using this. I do believe it helped promote healing after I had a little fin rot run its course. I use this after water changes (stress) or when I need some extra juice to amp up healing. It’s affordable and very easy to follow the directions.

A must have for Discus
So just to clear things up for anyone who is unsure. Paraguard & stress guard can be used together. I recently got back into discus and in knowing how sensitive they can be I wasn't sure what to use during quarantine. I watched a couple of videos & did some reading & reviews on line & the paraguard was highly recommended. There wasn't anyone using it with stress guard but I figured I'd give it a try. So here is how I used it. I ordered the first 7 discus & I didn't do as much research on the seller as I should have (I won't mention sellers name but just believe cheaper is NOT the way to go) anyway when I got them they were skinny, doing a whole lot of rubbing and 2 had ich. That being said I turned the heat up to 92°(this high for fish who can handle high temp only) & treated with both stress guard & paraguard for 2 weeks (put temp slowly back down to 84° when done).All fish survived & are doing great. Now as for the second batch of 9 discus . They came in healthy (more reputable seller) so I did just 3 days of both. Now if you are doing a 2 week quarantine like you should if you see any trouble you can restart both until you see they are doing better (2 weeks if sick is best). Make sure you remove carbon from filter when using paraguard. If your using stress guard alone for injury you do not need to remove carbon. I hope this helps . I highly recommend both products

Good but STAINS
This product worked well for my male betta. I'd been trying to help him with fin nipping and I didn't know what to do. Someone in a betta group recommended I try this and I am SO GLAD I did. It worked wonders! His fins are healing nicely. I haven't seen evidence of fin nipping for awhile now. I used it daily for a week and a half. I now use it for other my other bettas if needed. However, this STAINS things easily. The top of my washing machine is stained from it. So if you use it make sure you do it over the sink and place a cover down to put the bottle down. It leaked down the bottle and stained it. Overall, I love this product so far. The staining is unfortunate though. He's slowly healing. Using it for another nipper and so far it seems to be helping for him too. I'd give it a 5 star if I didn't stain super easy.

Had a Betta fish with fin rot. I made sure to change his water 1 gallon in the morning, 1 gallon at night in ( 3 gallon quarantine tank with heater a bubbler bare bottom to clean out poop with turkey baster everyday) adding 1 ml of stressguard in his water every 24 hours. 1/2 teaspoon AQUARIUM salts DILUTED in each new gallon of water added. treating water with PRIME ( 2 drops per new gallon each plus 2 drop every 24 hours for the gallon that stayed in the quarantine tank) The results were almost immediate! He stopped shedding, splitting his fins, getting his color back. 4 weeks later all healed. Lovin it!
