Hey guys. Woke up this morning to find this on my german blue ram. They always have had a random spot but I have never seen something like this. I have had them for about a month now and they eat just fine and love swimming around their 75 gal tank. Everyone is peaceful. Their tank mates are 4 glo tiger barbs, 3 glo tetras, 4 cory cats, 5 young clown loches (just growing out in this tank then will be transferred), 1 kuhli loach and 2 ghost shrimp. Tank has been fully cycled and is 3 months old. Water parameters this morning: PH low: 7.6 PH high: 7.4 (assuming somewhere at 7.4-7.5, the GBRs were raised in 7.4) ammonia: between 0 to 0.25 Nitrite: 0ppm Nitrate: 30ppm
