He's still eating. Looks like fungus to me...water is 78 to 80 degrees. Sand substrate. 3 chamber sump with filter pad and lava rock. Pathos bog ivy in display tank. 7.9 ph. 0 ammonia. 0 nitrates. 20ppm nitries.
1 -3 inch flower horn
2 - 6 inch common plecos.
75 gallons in display. 40 gallon sump. Sump runs with about 20 gallons of water. No other fish showing any sign. This sighn started showing when he was in a different tank been in this tank about a 6 weeks.
Thoughts?
