I have 2-1 inch bottikoferi. upon receiving them I noticed one swam with slightly clamped fins and faded color but figured it was due to stress of being shipped across country in 24 hours. now fast forwarding a 4 or 5 days he still remains semi clamped and fins down (he will perk up and dart after food or across the aquarium), less active and almost always be sitting at the bottom, while the other is much more active,appears to have grown a quarter inch and almost double in girth while being more colorful. yesterday I noticed both fish scratch at the bottom, the smaller twice, the larger once but neither has done it since that ive noticed. Today I noticed what appeared to be stringy reddish/white feces floating in the tank but I couldn't swear to it as its very small and there is tannins in the aquarium from driftwood and the feces was moving fast due to pump current... Do I have an issue to deal with or have I read to many parasite threads? Thank you in advance for your replies.
