well the i just purchased a school of tiger barbs (sm.) recently and then added 3 (md.) more today. 2 of the 3 md. size tiger barbs acted perfectly fine with the community that was already there but the one other one keeps freaking out. well not really freaking out but he swims facing down or on his side, away from the school, and im worried that he might be seeing his end. could it be that its pregnant? a friend of mine says her grandmothers fish swam in those patterns when it was about to lay eggs but im worried that it doesnt apply to my tiger barb. does anyone know what i should? even though its one in many i still care for it.
