1.0 out of 5 stars | DEAD FISH IN 4 HOURS!!! residue
Color: Black With Fluorescent Highlights
These rocks were added to a established tank. I have had this tank set up for almost a year. I rinsed the rocks over 4 times and conditioned the water the last rinse. All the other items were added last week. After adding rocks today, the fish were dead when I checked on them 4 hours later. DO NOT PURCHASE!!!!!. The picture show's most of them stuck to the inlet filter after they died. I am so disappointed. I have been in this hobby for more than 25 years and have never seen a product do this. I would give a 0 if I could. UPDATE: I was waiting for a response to work this out before I posted this. A couple of days after this devastation, I went to put the bucket away and found this weird reflective residue in the bottom of the bucket. Now, I swished and rinsed this rock at least four times before I added to my bare bottom, completely established tank. There is no doubt in my mind that my fish died due to this gravel. I feel that I should be refunded for the two bags and gravel and for the all the adult fish that I lost. I planned on breeding my Neon Tetra's this summer, but they're gone now due to this gravel.

1.0 out of 5 stars | This gravel is POISON. It will kill everything in your aquarium.
Color: Pink/Green/Blue Fluorescent
This gravel killed all our fish and African dwarf frog. Do not but this. Amazon should not allow this to be sold. Horrible product that poisoned our tank. We bought a 3.5 gallon tank for our 6 year old son as a birthday present. We started with 2 fish and a frog. My husband and I both had aquariums when we were single so we have experience and know how to set up a tank. We cycled the water. We had a filter, a heater, and air pump. We tested the water with the water testing kit. So the water was well prepped. Next we decorated with this gravel as my son picked it because he loved the bright colors. We also put in two decorated plants and a little cave for the frog to hide in. After this was done we put in the fish and frog. After a few hours the frog seemed be sick as he was swimming like he had a stroke. We thought we may have bought a sick frog. We returned it to the store and they let us exchange it for a new frog. We had the water tested at the pet store and they told us the water was fine so we thought it was the frog. In goes the new frog. Next morning the frog and the two fishes which were guppies were dead. So we cleaned out the tank and cycled the water again. Did everything over and went to get new fish. We got three zebras. At this point our son was pretty upset that the frog and fish were gone. We told him they were sick and we took them back to the store. The zebras all died within a day. We just couldn’t figure out what was causing the fishes to die since the water tested fine and the temperature was good. We cycled the water again and started over. This time we bought two Sebre Tetras. One of the tetras was dead in the morning. The other was still alive but seemed sick cause it was not swimming around. So we thought something in the tank must be poisoning the water. So by process of elimination we decided to take out the gravel and cycle the water again. We put the sick fish back in the tank with out the gravel. After a day the fish was all better. It was swimming and eating. So in conclusion, the gravel was poisoning the tank. DO NOT BUY THIS GRAVEL. I would give it zero stars if I could. We bought new gravel and now have three tetras including the fish that was sick and they are all doing fine with the new gravel. Amazon should not allow this product to be sold on Amazon

1.0 out of 5 stars | This killed two Bettas!
Color: Black With Fluorescent Highlights
I had set up a 2 gallon tank, all with proper setup, de-chlor, etc. Put a Betta in, and he was dead in 12 hours. I thought it odd, as they are pretty hardy, so I brought him back along with a water sample. My water tested just fine, and I got another Betta, he was dead in less than 8 hours. I went back and read some of the reviews on this gravel, and wish I would have done so before.....others have had this issue too. I threw out the gravel, cleaned the tank, bought gravel from the fish store WITHOUT paint on it, tested the water again, and all was good, AND my fish is still alive going on 12 hours, happy and swimming around. There is something with this gravel, even with rinsing it completely. Do not buy if you want your fish to live.

1.0 out of 5 stars | Terrible
Color: Solid Black
The rocks are evidently coated in black paint? Which chips off VERY easily and floats at the surface of the water in little flakes. No matter how much you rinse it, more keeps coming off. I didn't even want to chance putting my fish in with it and having her eat it and get sick so I had to dump it all out and clean out the whole tank.

1.0 out of 5 stars | Sad!
Color: Solid Black
So for a whole year I had my daughters betta (Blue) living in a 5 Gallon tank with no gravel or anything. Decided to give this a try, as I wanted to put plants. Washed it and let it soak before putting it in the tank. Removed Blue from the 5 gallon and set up the tank with gravel. Blue was curious and observant. Got home the next day and Blue's tank was super cloudy. I was of course scared and searched for Blue. He was dead. Never once did I have a cloudy problem with this tank and the levels were great. I also have gravel in my 20G with live plants and no issues. I am super disappointed in this purchase.
