Little fish + big aquarium + lots of plants = where did the fish go?
I counted 13 otos earlier today. Saw as many as 11 tonight. When I bought them I said I would be happy with keeping 8 or 9. Right now, I want all 13 to live. I can also see some clear places where otos have eaten the brown algae (diatoms?) off the leaves. Yay! See why I love the little guys already? They are adorable and useful!
I tried counting neons, too. No luck. In the evening, they like to settle in among the plants.
I think neons might be engaging in courtship/spawning behavior. Not sure. I did find eggs the other day on the glass. Don't know who they belonged to.
I don't think I will get fry or wrigglers. I'm not trying to, either. But, breeding fish are happy fish.
Despite no water changes in 11 days, my nitrates are falling again. They spiked to 10 a couple days ago but are back down to 5 ppm again. It's crazy to me because the 20 gallon had nitrates around 40 to 80 all the time. If I didn't change the water every two weeks, at least, then water quality went downhill in a hurry.
It must be all the plants. I mean, I knew that could happen but it's still shocking to me right now. The plants are obviously growing. I can tell when I look at pictures from a month ago when I planted them. I've got the sword plants in the middle that have leaves that have grown at least six inches! The pictures here show how big they are.
And, to the right is what the tank was like when I first put in the plants. That's a huge difference for one month, I think.
