NeonNeptune
Fish Fanatic
Some of my bigger neon tetras look like the red strip is almost starting to "leech" into the tail fin and anal fin. Even the dorsal and pectoral fins have a little orange coloration that seems to have developed over a long period of time. Is this just a sine of them getting older? I have had them for a long time and they almost look like jumbo neons. And these changes are only affecting the bigger ones.
