hi,
my family set up a fish tank two days ago. at the aquarium shop we were told we need to cycle our tank with some fish in it, and we bought 5 neon tetras and 3 corydoras catfish that are about 2cm long each.
our tank is 250 litres or 66 US gallons.
i noticed this morning that one of the tetras was acting strange, he was swimming upside and rolling around. when i came home from work i think i found him stuck on the filter. there was also one other neon tetra that disappeared and i cant find him.
an hour later i noticed another fish starting to act the same way, and was breathing really rapidly and coming up to the surface of the water very very often, he died after 10 minutes. there is only 2 tetras left and i am worried they might die too.
i dont really know what to do, or how to help them. i dont have a water test kit and i cant get one until a few days (ordered it online) as i work until 6. could this be an ammonia/nitrite thing??
