So it's been almost a year with my tank and I've honestly done nothing but just let it run by itself and i love it! However, my fish don't give me that extra color I was hoping for and wanted just a little excitement. I've always wanted guppies and to breed them(not for sale but for food for my bigger fish) but don't know if they would work. Also, I don't want to screw up my beautiful tank. I'll leave my current stock below and add a picture later! Current stock: 1x Bristlenosed Pleco 2x Angelfish 3x cherry barbs 3x pearl gouramis 5x red serpae tetra 5x Indian arrow glass heads 5x black neon tetras All in a 55 gallon with plenty of plantation!!! Thanks for the help!!!
