I posted a few weeks back that I was having an issue with fish breathing a bit hard. I thought perhaps they had gill flukes, but after weeks with no deaths, consistent PraziPro treatments, and heavy water changes, I'm thinking parasites are not the problem... but the heavy breathing persists with some fish. Can you check out the video I made on youtube and let me know if my filtration is inadequate or if I'm not positioning the output in such a way that there is enough surface agitation? (note that the fish aren't really breathing hard in this video because my pump was on before)
Here are some notes:
- Tank is 90 gallons
- I am not running CO2
- Running a Fluval 406
- I do a 30% W/C every week
- My levels are always at 0, pH about neutral
- nitrates never seem to go above 5ppm, or whatever the second color corresponds to on the API test chart (can't recall, but I think it is 5ppm)
- Water temperature around 79
- As you can see, lots of live plants
- I do not have a lid on my tank, so gas exchange should be fine
- My stock is listed in the Youtube video description
- I have 4 more Boesemani in a hospital tank with plenty of O2 until I figure this out, as they were particularly affected. The remaining Boesemani is spending a lot of time in the flow of the filter output.
I just set up a Whisper 100 air pump today and it is way too strong, even though this is a 90G tank. I did note that the fish WERE NOT breathing as hard after I ran it for awhile. Could it really be that there's not enough oxygen in my tank? Should I bring my filter output up so that there is more surface disruption? I am going to exchange the pump for a smaller size that won't be so powerful, regardless.
PS - sorry for the terrible and creepy sounding narration in this video, I'll do a better job next time
