I have had my Betta just two weeks, he was very active when i got him, in the last 24 hours he has completely changed. He is in a 7.1US Gallon tank with a filter and heater. He has two cave like houses, which he had hardly been in now he just sits in them moves occasionally from one to the other. Temp is near enough 78.
I can't work out if his beginning to fade in colour, scared its the start of ick, as around his face/mouth seems more white then before.
Was not sure whether it maybe stress, how would i treat this?
I have tested PH and Nitrate both are fine. He currently gets fed pellets 3 times a day, he still eats as normal. He seems to sit in either the caves or in the bottom corner of the tank, very still could be mistaken for dead.
Im very nervous has i have become attachedvery quickly and dont want to kill him. Please send urgent help or suggestions.
