Hello everyone, I have had a male veil tail betta (Haku) from my local fish store for 3 years now, started in a 3.5 gallon filtered and with an LED air stone being fed Tetra Betta Plus pellets. Tank was already cycled. Almost a month ago he upgraded to a 10 gallon filtered and tank now with real plants instead of fake. I have java fern and amazon sword. He's been swimming solo since I got him except for a gold mystery snail which sadly didn't last longer than a day, cause of death unknown. However I've been struggling with knowing about his health since I got him, his fins are always ragged with clear spots where it starts to grow back. I know it's not his decor, I had him in a bare tank to test it and fins did not improve. He has also developed some gold spots which don't look like velvet pictures I've seen. There's no black on his fins so I'm not sure it's fin rot. Recently I added blood worms to his diet, but it's still been difficult to get him to eat. I feed 2-3 pellets twice a day, then a few bloodworms with two pellets every couple days. He sees the food but won't eat. However, he is not lethargic and is always swimming and exploring. He also seems to have a clamped pectoral fin, but that's the only clamped fin I believe he has. He has a bit of bloating and gills appear dark sometimes. He also has shimmery turquoise scales that seem to come and go. Please view the pictures below and let me know what I can do to help my little guy, or if he's healthy. I've never used a heater except in the winter because his tank is naturally kept at 80 degrees. Most recent water levels: Nitrate- 0-20 Nitrite- 0 Hardness- 150 Alkalinity- 80 pH- 7.2 If any other information is needed please don't hesitate to ask.
