Can someone help me out? What should I do? I'm doing a 100% water change since I saw that the Nitrite levels were really high. 5.0PPM, and my Nitrate levels are 15PPM, my tanks nearing the end of its cycle.
Everything in there is soft enough for him, the schedule is a little iffy but he does have things to hide in and behind, he has a silk plant with large broad leaves. I might be getting some live plants for the tank, I'll look into the mirror, and I just put a baffle back on to the filter.Looks like he either got snagged on a filter or decoration or he's nipping his fins.
Go over your decorations with a stocking. If it snags, it'll rip fins.
If he's nipping his tail, make sure you have a set schedule for night and day that you don't stray too far from. Make sure he's got things to hid behind/in and explore as well as time to exercise any excess energy.
A hand held mirror is a good tool to get some exercise and boost self confidence. Make winning easy at first, but slowly work them up to a minute or two of flaring before taking the mirror away.
Plastic bottle caps are also a good source of entertainment. You can use different colors to see which your betta prefers.
