Hi there, I am new to having Orandas, but I have had experience with other fresh water fish. I have always loved Orandas and I was so excited and did a lot of research before purchasing. That being said, I am worried about my new babies, here is why... When I purchased my orandas, I purchased what appeared to be three very healthy fish. Sadly, a few days after bringing them home (maybe 2 days) the littlest one developed a bulging eye and a few days later I noticed it began to show signs of Dropsy. I made a hospital tank for the little guy and did everything I could. Unfortunately he passed. The other two orandas (Charlie Chaplin and Sharky) seemed perfectly fine. Now I don’t know if I am being paranoid, but I am worried about them. Charlie is mostly white and I am noticing he has visible veins in his tail. And today, I noticed Sharky (red and white) suddenly has a dark red spot on the side of his head and is starting to have dark red coloring on his fins. Here is their tank situation. I hope this is all normal growth/color change, but I don’t want to leave it alone if I should be treating them for something! Thank you!! I have a 45 gal fully cycled aquarium. Ammonia-0 Nitrite-0 Nitrate-5ppm ph-7.5 I do weekly water changes, about 50% the two orandas are juveniles. Charlie is mostly white and his body is about 3 inches (not including tail) and Sharky is red/white and is about 2 inches (not including tail). Food - repashy super gold gel food, and Hikari oranda food. Live plants, sand substrate, 2 hob filters 500/ gph I hope I have provided enough info and not too much! I tried taking a picture of Charlie’s tail veins and of course now they are barely visible!
