Iām relatively new to the aquarium hobby but Iāve seen that my fish are having a weird behavior. Iāve had a 15 gallon tank for 3 months now and I have 5 neon tetras and 2 of a little bit of a larger species of tetras(I donāt remember the name) and their all doing fine but the 2 larger tetras are having āhiccupsā since when I got them. They swim around and are very active but whenever they stop they have a sort of up and down motion. I was wondering if anyone knew what the problem was
