hello i have a 20 gallon high with 12 blue silvertip tetras
im looking for some centerpiece to accompany these fish i can decide on what id want as a focus fish.
i was thinking some pair of small cichlids? or gourami or something, could anyone give me suggestion?
i kinda want it a bit aggresive so my tetras are encouraged to school a bit more.
any help? thanks
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 completely agree. Deliberating stressing out any fish is not responsible. This weakens the fish's immune system, bringing on health problems, and shortens their lifespan.
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.
however you could consider a pair of kribensis spelling may be wrong
they will not make them skool tighter
nor will they be semi aggressive
but they are very territorial, in my experience i have only know mine to be aggressive with things that live on the floor of the tank like my weather loach do
provide a cave or two and they will even breed laying there eggs on the roof of the cave
look them up and check they are ok to live in your water parameters and see if you like them
