Ok Friday has some issues. His left ventral fin is looking brownish and sticking out funny. usulally it looks like this /( )\
as for formation of his vent. fins. now it looks like this /( )--
The parentheses being his body and the /s being his fins. He swims fast around the tank and won't calm down! Any ideas in how to calm him?
edit: It seems to help him calm him if I rub my finger on the glass and make a soft humming sound and he eats fine.
