free thinker

I have had these particular 6 fish for about 3 years all living harmoniously together. Today 5 of them started picking on one of their mates, attacking it and trying to bite it and cornering it! It's like a piscine Lord of the Flies in the tank. I have removed the fish to another tank for their own safety.. Can anyone tell me why the others have developed this blood lust after several years and explain what is going on and what on earth I can do about it? There are 6 fish about 2-3 inches long in plenty of water(80litres) help please....

I use it for emailing, web surfing, and office stuff (word processors, excels, powerpoints etc). I don't need a gaming beast with tons of high quality graphics etc, but I do like my digital photography. I'd like a fast processor and quite a large memory (500G) Oh and a reliable wireless connection would be good too (my ipad never loses connection but I'm not that keen on a mac for my computer)

their tank is about a 40 litre one, and I'm finding changing the water a real chore - emptying the whole thing into the bath, rinsing and sifting the gravel etc.. is there an easier way to do the whole shebang...How on earth do people clean out the huge tanks??

would you let your 11 yeaqr old daughter to use a nasal hair trimmer on you...? Help... she's approaching fast with menace in her eyes...

And if so how do I do it? Or are they just for live streaming?

Annoying antiSpyware windows and companies offering to clean up my hard drives keep popping up. i certainly don't want to open them up as goodness knows what will come flooding into my computer. I can't seem to get rid of them even when I try to delete them from my c drive - they keep telling me access is denied and I can't do it. is there some software i can either buy, or download that will help me get rid?

Is it gentlemanly behaviour to expect her to do all the work while i lie back and enjoy. My leg's strapped up and find mobility a problem. Evrything else in good working order though
