So a few months ago I picked up 9 black neon tetras and everything has been going well. A few weeks ago I noticed two of the tetras looked like they were eating to much and becoming bloated (All the others looked normal, I do the one minute rule with the food). Now both of these fish look like they are going to burst soon and it actually looks like I can see eggs inside those two fish. I know tetra are hard to breed and I'm not really interested in increasing my community numbers, so what should I do? Just leave the eggs when they lay them and let nature take its course? Do I need to buy a fry cage or would the java moss be enough for cover?
