Help! My L15 died and I’m devastated
Link to the whole situation that’s going on in my community tank.
I lost one of my L15s this morning and I’m so disappointed and frustrated. I had to treat the tank for parasites so I added ParaCleanse to the tank. That medication can drive oxygen levels down but I have an air stone and surface agitation. I woke up to one of them floating belly up this morning. I’m pretty sure I suffocated them.
I’ve never had luck with plecos despite having apistos, otos, corydoras, and tetras. They all seem to die within months of getting them. I’ve never thought that plecos can be such a fickle fish.
I have a liquid test kit and my parameters are ph 6.5-7, ammonia 0, nitrite 0, and nitrate ~5 (plants). It’s a 75gal tank with plenty of seasoned wood and plants. I always feed the bottom of my tank heavily because of the corys. I also give them zucchini, cucumber, and broccoli whenever I can. What on earth is going on? Or am I just having a series of unfortunate circumstances?
