Question

[eastern aquarist]

I have 2 oscars 13cm and the other about 9cm and 2 green terror both are same size 10cm, one commin pleco 8cm i was thinking of buying a silver arowana
Tank size 428 L
Can i keep a silver arowna with them ?

If I'm correct 428L is about 113 gallons? Which is an odd size I don't think I've heard before. What are the dimensions of the tank?

I'm sorry but if it is just over 100 gallons it's too small for the fish you have now long term and definitely way too small for an Arowana. Aro's can also be jumpy and the cichlids could definitely spook it into launching itself into a tank wall or cover or out of the tank completely.

In a word, NO! You are overstocked as it is. That size tank is barely 100g, just right for one full grown oscar, so you're way off the sensible stocking mark. Have a serious rethink.

where are our manners?
welcome abroad ,eastern aquarists.
As mentioned above, you are overstocked and definitely need to reduce some of your existing stock.
