Ok so I added some all natural rocks to a 220. Some are slate and others are just rocks that I thought were cool looking. Anyway the oscars that are in the tank spend a lot of time sitting at the bottom of the tank. They are still interested in food and for the most part seem healthy. There are also 2 flowerhorns that are acting normal. Just a bit worried. By the way all water tests OK. if anyone has any thoughts I would love to hear it.
Thats funny.....I never would have thought of sulking fish
I guess I should have expected it from an oscar
