For the past week I have had 5 neon tetras in my 29 gallon tank and they have been doing amazing. I added 7 more today to increase my total to 12 and now there seems to be one neon tetra that has gonna very large in the belly section... could it be ready to spawn? Anybody have experience with this? I wish I could take a picture but after spending 15 minutes on that and getting nothing but blurry blue lines I gave up....
