Tiger Barb Establishing Senoirity?

[LOVIE]

Hello All I'm new to this so please bare with me. Last night, two of my male tiger barbs decided it was time to establish some senoirity in the tank. One is about 1/2 inch the other is 2 1/2 to 3". From what I read on the net it was normal for them to lock lips and twirl or fight and so on. Well this morning the larger of the two is floating on his side (like he can't move but he's still breathing and still wiggling, not swimimming) and although I can't see and visible injuries i'm sure it was because of last night's situation. What should I do? Should i put it out of it's misery? I already moved it to another tank to prevent the smaller male from harrrassing it. Help! :help:
THanks in advance

It could be a fight, but there are still other possibilities. Just to check, what are your ammonia, nitrite, nitrate, and pH levels? Also check the temp. If its none of these it could of been a fight.

Kasakato,

Thanks for the advice. The fish died about 5 minutes after I posted the thread. I guess it was a fight. My levels are fine by the way, and so are the other barbs in the tank.

Chances are it was trauma from a fight then. If you have 8-9+ of tiger barbs it should be ok. This will reduce fighting and keep everyone happy. But only do this if you have the room for them.
