160L, but i heard that tetrazona bite the antenas of ancistrus/
is it real?
They're not antennae, but rather the "bristles". No, they don't. They bother mostly the fish dwelling in the mid and surface levels. I would rather go with pentazonas than the tigers. The former is more peaceful whereas tigers can limit your choices due to fin-nipping issues.
Did you mean the angelfish(Pterophyllum scalare)?:) If so, I'd choose the scalare rather than the barbs.:) They're more stunning but this limits you the choices of getting tetras. Scalares tend to eat slim-bodied tetras like neon tetras but there are lots of choices available. I'd recommend you try diamond tetras(Moenkhausia pittieri). They're stunners.
Diamonds are deep-bodied characins and are absolute stunners especially when mixed with angelfish. Cardinal tetras are also good options as they grow bigger than neons but a bit more expensive.
So, after some deciosin my aquarium will be 112L. 70/40/40.
I would like to put tetrazona with neons. I heards thet if you pu tetrazona after neons, they will not attack.
Can i make thc combination possible?
