Hey everyone! Right now I’m doing 75-80% WC every 5-7 days. I did one on Friday, today is Monday. it’s been 2 feed days so far- 3 to 4 days after changing-and I noticed two new things:

1) the del looks like she has the beginning of cloudy eye
2) the polli has a new white “thing” on her side. It appears to be a scrape or scales looking dull. What could this be from?

First thing I think of is water quality. Here are the test results:

Does The ammonia means there isn’t enough B.B., I fed too much, or there’s too much nitrate?
What do I do?

Seems pretty high after a 80% WC on friday(3 days ago). Is there anything that can be done about this in the 55gallon tank?

My intuition is telling me the bioload is too high for the tank. I have 4 polys that are 9-10+inch and the albino is 6.25in. I’m really wanting to upgrade to a 90g. My parents are pretty anti this until I get my own space again;however my main concern is the health and safety of my animals. Is the 90 gal a necessity at this point? Will that be big enough? Any advice would be appreciated.

That does seem really high for feeding every other day and doing that many water changes. You shouldn't have ammonia and those nitrates are high for that soon. :(

I can't remember if your tap water has been tested for ammonia or nitrates?

If your parents won't go for a 90 gallon, I bet that even moving to a 75 will help notably. And you can get those for cheap, and they really don't take up that much more room. Obviously a 90 is better than a 75, but....

So you have 5 polys, some congo tetras and giant danios? (How many of those?)

What is your filter and how often / how do you clean it?
