SunGrow First Impressions

"No issues so far though."

The structure is roughly 14l x 6h x 4d. I was expecting this to be a thicker resin piece. In the 5lb box, I got two large, a medium, and a small piece. The resin color is dark, so no repainting needed. I switched up my plans a bit and everything was lovely. They get tossed around in shipping and chunks break off. When I opened the box I was so surprised and shocked.

Qguai First Impressions

"It's not a huge piece."

I got these for a betta sorority tank. You should never buy rocks but there's no Dragon stone down by the river. Dragon stone has a nice reddish tone to it so it really stands out. I was very pleasantly surprised with these dragon stones. No I dont work for them and no I dont get anything for saying that. I couldn't find these at any of the aquarium stores near me, chain or independent. They are making these by sloshing resin around in a mold, so it's really thin.

"Exactly as pictured."

They are making these by sloshing resin around in a mold, so it's really thin. The holed rock formation is a nice design, but the material being is way too thin. It was well worth time and effort to get them clean. I am only giving 4 star because I had no way to request a larger stone after order. Love these rocks and you usually get 1 big, 3 Med and the rest small. Overall, a great natural-looking stone in an aquarium. They get tossed around in shipping and chunks break off.
