Received a good handful of guppy grass. Some of it was dead/brownish, so I tossed it. As long as some of it survives, you'll be set. This stuff grows very fast like duckweed. Definitely no CO2 required. If you let it float, it branches and could fill your tank quickly. If you stick the ends in substrate, it tends to grow in one long strand and will need to be trimmed to keep it from becoming a ball at the water's surface. Be careful when you weed out excess from your tank. I had a platy get tangled in when I removed some and didn't realize I removed her from the tank until it was too late. RIP little fish :(Also, my mystery plants was the Riccia Water Spangles and I love them. My fish ate the frogbit and water spangles I ordered separately, so it worked perfect. I would definitely buy from this seller again. Just wish it was a bit less expensive.very nice product. Fast delivery, all plants look healthy. So far they grow well in my tanksThe guppy grass broke apart a lot and I ended uo taking it out because it just keep breaking into smaller pieces. I'm still giving a 3 star because the bonus plant is AMAZING. it was a type of lily pad looking small plant and it has grown so beautifully in my tank!I have been looking for guppy grass for months. So when I found it here I was very happy. Unfortunately it has been very hot here. I waited to place the order until cooler weather was forecasted, but two days after I ordered the weather turned extremely hot. When the package arrived I was thrilled to see the very healthy portion of guppy grass was packaged well and was still alive. I immediately dropped the grass into fresh room temp water and it has been great. No melting, no wilting and no snails. This is quality healthy plants. The bonus of frog bite made the order perfect. I will definitely order from this seller again.We have had the guppy grass in our tank for a few months and it is so huge now! It’s growing beautifully and the baby guppy’s are all having somewhere to hide and grow big at now!Was alive and it doing well in my tank love itGuppy grass was packaged well. Upon arrival it was green and healthy looking. I usually fund some insects or snails on my online orders. But, the guppy grass was hitchhiker-free!! I also received red root floaters as a free gift which is a plant I've been wanting for a while. So that was a pleasant surprise. I absolutely will order again!My guppy grass has grown so much, and the quality is wonderful. I didn’t think that it would grow so nicely, but it has and I would but from this seller again.
