How big is your tank. In gallons please. Maybe the new fishie is a bully.

Has he darkened in colour, does he look bloated.
If he hiding away something wrong from bullying to desease.

He's looking fine and quite healthy, good colour. It appears they take turns to hide in the castle, we have now noticed. Not sure what theyre doing. It seems as if theyre guarding something as only two of them ever come out at once.
