Gsp tank mates

[micalbrown]

I have 2 gsp and 1 figure 8. I just introduced 2 mono argentis to the tank and one of the gsp is acting super weird now his belly stays white but is really reserved now. Should I worry or will he be fine over time?

What size tank? Also Fig8 and GSP cannot be tank mates forever.

+1

Figure 8's need a low-end brackish environment....GSP's need a high-end brackish environment

What size of tank are they in,...a 55 gal tank would be necessary for just the 2 GSP's

I decided to take the monos back. I was wondering why the gsp and figure 8 cant be tank mates?

[Blaine]

F8's need low-end brackish water to thrive and live properly (1.003-1.005)

GSP's need high-end brackish water to thrive and live properly (1.018)

They are simply not compatible over the long term, they have different needs and requirements.

In addition to Blaine's explanation of the different SG requirements, GSPs grow 3x the mass of the F8s & will be much more aggressive.

+1 to PP's comments, but minor correction on relative masses - double the length gives about 4x the mass, so GSPs are much larger, more aggressive, and need higher specific gravity.

I thought even 8x the mass given the same body proportions, since it's twice as long, twice as deep and twice as high... 2x2x2.
