There are weird red lines visible on my oto's belly. The lines make a little diamond shape right between its pelvic fins. There is also some red where his pectoral fins meet his body. I first noticed this tonight.
My numbers are good: 0 ammonia, 0 nitrite, 15ish nitrate. The fish is otherwise active and eating well. My husband managed to catch a few good shots. He says maybe it's just the fish's veins showing through its skin. I'm more paranoid.
Any ideas on what this is?
