Fish count, rams fighting

I counted my fish tonight. I have taken to counting because my tank is planted such that it makes it difficult to see parts of the substrate. I had two otos die and couldn't recover their bodies so I try to make sure there's no dead fish in there.

Here's a current picture of the tank.

Fish count: 10 rasboras, 15 neons, 8 black skirts, 4 otos, 5 rams. I couldn't count the cory cats because they are fast and spend a lot of time in the back under the plants. So, other than them, my fish are all accounted for. Yay!

I'm getting some cloudy water. I think it' said bacterial bloom. I tested the water tonight. I found 0 ammonia, 0 nitrates, and 5 - 10 nitrates (all ppm). The test kit makes it hard to tell the difference between 5 and 10 ppm nitrates, but if I had to bet, I would say it was 5. The fish all look healthy. I had some fin rot going on ond the black skirts and he was swimming weird, "sliding" backwards and then twitching. He isn't doing that anymore and the fin rot is gone. The rams aren't flashing anymore, either. They look good. So, that's why I think it' said bacterial bloom. I think time will have it clear up.

Speaking of the rams, some of them are fighting a bit. I actually saw them make contact with their mouths a couple times. If you're not familiar, they come together and "lock lips" for a moment. It's a dominance behavior. I don't see any injuries, though, so I think this is not dangerous yet. I will keep an eye on it.

Can I just mention? I can't believe how low my nitrates are! I have tested my tap water and it shows around 20 ppm, maybe 40! So, even if I do a water change, I will have nitrates that are, potentially unhealthy. That' some reason I use Purigen, to remove them. But, I think the real reason I have so few nitrates is that the plants are eating them! Love that!
