Hey all, new to this forum since it's provided me tons of answers. But recently I've noticed my Half-moon Betta, Xavier, has been getting strange new markings on his tail, like little black dots or stripes appearing in the mid-section of his tail and slowly spreading to his anal fin.
Xavier has three ghost shrimp tank-mates, but he was already showing signs of these markings before I got them added into the tank.
Tank is a 5 Gallon with Heater and Filter, kept at 75-80 degrees Fahrenheit.
Mostly Silk plants, some plastic.
I have yet to buy a pH reader.
I use Stress Coat or Topfin's brand of Betta water conditioner. I sometimes change between the two whenever I do a full water change when he was once kept in a very small container several litres, but it's now used as his QT. But primarily, I uses stress coat, may buy Prime soon as I've heard many good things about it.
He still eats and swims around curiously, flaring normally
not lethargic whatsoever.
I recently placed him into the small Quarantine tank, several litres, little space right now.. and did a full water change in my 5 gallon, but I need to be sure because I don't want to place him back in his home and spread the fungus all over again.
I just need confirmation if this is Black Spot or Ammonia Poisoning.
