Ok, sorry for so long without reply, I was mistaken about the nitrates. Nitrates are about 15. The tank had already been cycled from a previous fish, and a colonized filter but has fresh water before this fish was added, this is why there were no measureable nitrates.
I am using
API '5 in 1' test strips (PH, Nitrates, Nitrites, General Hardness, Carbonate Hardness) and API Ammonia Test Strips.
He is not doing the swimming horizontaly in the pot often; I have only seen him doing it once (he is not floating though, he is swimming in place horizontally trying to hide). He is doing the 45 degree swimming in place near top though. He also likes to lay upright on bottom when he is scared or hiding (at moment, whenever I am in the room near tank). Still not excited about feeding time but does eventually eat (will now eat when I am in room but not standing by tank).
