Hi S
I used to have a brackish Tank with a couple of GSP in and they were brilliant, I really liked them
I have quiet a strange assortment of fish in the tank with them some Brackish and others I slowly acclimitized over in a quarintine tank over a period of 6 weeks
They were:
Green Spooted Scat
Mono Angel
Archer Fish
Bumblee Goby
Some of the Non Brackish Fish that I Acclimitised:
Freshwater Angel
Keyhole Chillid
Kribs
I got rid of most of the true bracks, but still have the :
Freshwater Angel
Keyhole
Kribs
Archer
Mono
In a brackish tank, have had these now with no deaths of fighting for 2 1/2 Years, the main success is the Freahwater Angel, when we bought here (cost £ 1.25) she was the size of a 50p pce (about a Dine) and she is no larger than my hand and is a beauty.
Saying that I would be careful adding any fish with sweeping fins like an Angel as they can become fair game to the puffers
