How many Black Arrows may I have?

[Riv D]

I have a 210 Gal. with a RT Gourami, 2 sm plecos,1 Frontosa, 2 sm Parrots.
I'd like to get 3 Blk Arrows.
Would they get along?
How long do I have till I have to down size ???
I used to have 1 and it died after it reached 18".
It was a very nervous fish and hit the top of the tank every other time you walked by it.
I'm wondering if having 3 will solve this problem???
Please comment.

a 210g tank isn't enough for 3 black arows.

i would say no...expecially with those fish... full growns need a 200 to be happy IMO and 3 plus those fish just doesn't work...thats just my thoughts tho im sure others will say different

Assuming you 210g has a footprint of either 6' x 2' or 7' x 2' It is really not big enough for a single full grown black aro, let alone 3 of them.
