This is a discussion on Centerpieces? within the Freshwater Aquarium forums, part of the Freshwater Fish and Aquariums category; -->
hello i have a 20 gallon high with 12 blue silvertip tetras
im looking for some centerpiece to accompany these fish i can decide ...
Im sorry but wanting slightly aggressive fish to make your tetras schoal tighter is a bit daft, it would put unnecessary stress on the tetras. If you want advice for what kind of fish centrepiece then iwould suggest putting up water perameters such as ph gh etc
Yeah tbh i mirror the post above. Thats just a plain HORRIBLE idea.....
A lot of tetras school loosely, thats just the way it is. If you want tighter schoolers, change them for something like harlequins that school very tightly.
Putting a bully fish in isnt going to give you your tighter school, just a smaller one as you stress them, and they get ill and die through it.
I think you might want to look at this as a time to decide what type of fish you want to keep - aggressive or peaceful. If you want aggressive fish, re-home your exisiting population and build a tank of aggressive fish. If you want to keep the fish you have, approach this as creating the happiest/healthiest environment you can for them (which would mean not purposefully inflicting stress on them) and enjoying their natural behavior vs. trying to contrive ways to mainupate their behavior to suit what you want to see.
