Will More Rummynose Make The School Tighter?

Angolangrl

I currently have 14 rummynose tetras in a 150 gallon tall planted tank and love them. Currently I have 8 angles, 5 glow tetras, 8 guppies, 3 torpedo rasboras, 1 hillside pleco and 1 BN pleco. I would like to add another BN pleco or hillside loach and more guppies. (I did read-up on the combability of the different fish and am aware of the potential issues. My tank mates are doing well.)

I just added the guppies and since have noticed that the rummynose tetras are not schooling as tight as before. My tank is planted and finally starting to take off. I have read that the more planted the tank the less schooling may occur. Is this true? If I get additional rummynose tetras will they school tighter?

In my experience, more fish=better directional shoaling behavior. That being said, when your fish are grouping loosely together, they are more comfortable and feel safe in the tank.

I doubt it. Less schoolingbehaviour only means one thing in my opinion = that they feel more safe / at ease. The addition of ditherfish made them feel that way.

Or opt.3 : accept they feel at ease in your tank !

Thank you.
Opt. 1 Then do I need another "big fish" like a rainbow shark or red tailed shark? If so should I have 1 or 3?
Opt 2: Should I trim the moss and plants?

Either of them tend to bully the other fish a lot unless they established their order, also most people say that they keep'em on low water temperature like below 75.
Personally believe me I keep one in 80 for past 3 and half years which is in my profile.

Often they might chase your plecos as well.

Sorry thought this post is new.
