Hello fellow fish lovers! I have 5 Buenos Aires Tetras in a 150 gallon tank along with some others (3 black Molly, 8 GloFish Tetra, 2 Pineapple Swordtails, 1 Cory Cat, 1 Pleco, 1 black Skirt Tail Tetra, and 2 see through fish[I'm not sure what they are]) I've noticed that my Aires Tetras are becoming very aggressive and I also brought some Neon Tetras home and put them in the tank and the Aires IMMEDIATELY went after them trying to nip them and eat them? I thought these guys were supposed to be friendly! They are not! Help! Has anyone experienced this? Also attatched is a pic of the see through fish, what are these?
