Tank Behaviour Changed Drastically

[tricky8]

hi. i done another post as this is worrying me also. 90 litres tank with ph of 8.2 seperate isssue i know which im working on! and amonnia 0 nitrite 0 and nitrate 40. on wednesday of last week i added 3 tiger barbs and 3 glowlight tetras to the tank which contained 5 neon tetras and 2 cherry barbs. now whats happening is one tiger barb is chasing the other two forcing them to hide all the time . if they dare to explore it chases them back sometimes they putting up a fight but most of the time running and hiding. im having difficulty sexing them as i find it hard to tell if they are male or female. the 2 cherry barbs couldnt care less they quite happy and 3 glowlights happy also but now the 5 neons have become the target also for this one very active tiger barb. its simply chasing them to where it wants them thats all. advice please

To kerb the 'aggression' of the tiger barb, you should have more, so that the aggression is spread throughout the group. With barbs I tend to find six is probably the lower limit.

should i add 2 then to make it 5.

As I said, its something you can try. With most species of fish, you will always have a dominant one, so spreading the aggression is the way to go. I don't know the dimensions of your tank, so I am not sure how many more you can go for.

I have seen so much aggression from tiger barbs that it is one fish that I won't allow in my tanks. My wife just loves them, but I like a peaceful tank where things like neons stand a chance of surviving. I don't know if more tigers would be better because I always figured "what if it doesn't help and I have twice the aggressive fish". I am really no expert on most egg layers but know that I don't trust tiger barbs at all. I think they probably earned their common name.

thanks im learning that now and im regretting it a bit but they do make the tank look better but im worried what its like to live in it for the others. it does seem to be calming but just wish the agrressor would let the others come out. they feed ok just cant be sociable. if i knew if the agressor was male also would help and what the sex was of the hiding pair
