So, I am watching this video on youtube:



and notice that this is a 250 gallon tank with at least 4 oscars I count in it, and i see 1-2 blood parrots in it as well.

Is this considered "safe?"

I ask, because as a backup plan if I need to rehome my flowerhorn, is this advisable? Could I replace my flowerforn with 2 more oscars?

Cheers,

J

To me that's 220gal just for the O's and they have 30gal left
I would imagine that they would have unbelievable amount of filtration
But I have never owned a blood parrot and I have no clue on what the require

Understood. That is why I asked. I love points of view.

My hopes are that my sump will be "massive" too.

If it was me I would go one for one ...
Like take one blood out and put 1 O in

basically, the main issue of over stocking is water quality... and
space consideration wherein limited space resulted into bullying...

i have this experiment wherein a massive sump tank servicing several
display tanks or one big tank with divider to avoid space issue... i found
out that we can maintain water quality; avoid space issue by a divider;
and keep all fishes healthy. the only disadvantage of the set up is that
once one tank is infected, it may affect all other tanks too....

i will be posted that study soon... including the PHD Tank Layout and Design.
