Review on 🐠 Enhance Breeding Success with Penn Plax Fish Breeding Grass - Fry Hideout & Safe Haven - Stunning Decorative Aquarium Grass by Maria Taglienti

If you have a HOB filter, you need to attach it to some part of the aquarium somehow. I threaded a piece of air tubing through the mat and then tucked both ends under the lid. Aside from that minor flaw, it works great - I cut it in half and put half of it on the bottom, and the combination of safe surface and substrate hiding spots saved a lot of small guppies and platybrood in my tank. This is good if you're aiming for more natural, less stressful maternal births - breeding traps will save a lot more brood but really scare mums, I've actually had 2 new mums die in it while none have died if I would just let them give birth in a tank of tribal grass.
