Normal fish behavior?
I've been noticing my Dalmatian Mollys have been at the surface lately gasping for breath, but when I test the water perameters everything is perfect. PH is almost always smack on 7.0 and ammonia and nitrites are at 0, with nitrates at a fairly low 10. Is this behavior normal for any type of fish to do occasionally?
One of my otoconclus has also been swimming a LOT around the back of the tan. I know Otos can be quite active but I'm unsure if it is normal for them to do this.
I'm rather new to the hobby so I'm still learning fish behaviors, please bare with me.
