Ill Tiger Barb?
One of my Tiger Barbs has lost a lot of is colour over the last few days, i keep seeing it 'shivering' and floating at weird angles mainly with it's nose angled directly down.

Just 5 minutes ago one of my other Tiger Barbs was nibbling at it from what i could see while it was in that position, i have no idea what to do as i've just relocated a Blue Gourami that'd been bullying a few of the other fish into a 35litre tank and i dunno whther to leave the Barb where it is and hope for the best or to risk putting it in with the aggressive Gourami for a few days.

Help please? lol

Unfortunately, tiger barbs are well known to kill each other. For whatever reason, a fish gets ejected from the school, starting a long and drawn out death. The others will pick on it and prevent it from eating, eventually killing it. I have tried to rehab and reintroduce them, but they meet the same fate. I ended up euthanizing them when they got ejected. I kept them for years in tanks from 10 to 55 gallons, species only and community, as few as a few to as many as 15, and it made no difference.

Good news!

I was in my local pet shop and one of their more knowledgeable staff (i presume) suggested it may be a parasite rather than a water issue, so i treated the tank with a parasite treatment i already had.

Lo and behold she's back in the group (which has now been expanded to include 2 Green Tiger Barbs, which are stunning!) and swimming with the others normally. Even fighting off one of the Green Tigers that tried to bully her about.

Is 7 a good number for Tigers?

What gave you the idea it was a water issue?

I hope that's what it was (though treatments don't usually work that fast...), but if it's like I explained, it's a long and drawn out process that takes several weeks. Fighting back against the bully is not necessarily a good thing, and can be an indication of where the troubled fish is at. In this situation, fighting is a last resort - it's fighting because it has to - it's fighting for it's life. Just keep an eye out.

This fish DOESN'T want to fight, but it has to.... it was bullied into the fight.

Wow that was an interesting watch.

The behaviour i was seeing was slightly different, in that they only showed interest in attacking her when she was practically floating vertically, looking like she was on the way out. Now she's levelled out a bit and seems to be swimming a lot easier they aren't bothering. I just keep seeing the odd dominance fight, my Greens wanna take over but the boss of the normal Tigers isn't allowing it.

I'd read that if the water has issues such as high nitrate levels it can aggrevate the fishes gills, causing that twitching behaviour but i used the parasite treatment 2 days ago and the improvements coming day by day. Have to use another course on Thursday and then hopefully all is well.

Those Tiger barbs look quite big, makes me look forward to mine being all grown up!

If it was a water quality issue, they would all be affected in some way. "High" nitrates is relative. IMO nitrates are the boogieman. I often see people suggest that nitrates are the problem (when they aren't THAT high), and I think it's a real disservice to the person with the problem, as it derails their search for what the real problem is. Besides, any time you suspect a problem with your fish, the first thing you should do is a water change. If it's really nitrates, then problem solved, right?

Yeah thats what i did and nothing changed, so thats when i decided to ask at my pet shop and got the advice to try the anti-parasite treatment.

Just gotta hope this is the end of it, they all looked stunning earlier in a nice little shoal.

Yes, they are beautiful fish!

Good luck
