Yes There is a FTR in there its called PJ and its 6 years old i got it i weight 83g and last time i weight it ( last year ) it was 1.3kg the light i use are T5 54w with a full spectrum. thats in the day time.
In the evening till around 11:30 pm i use 2 Nan light its much more soft kind of light and it is supposed to help bring out the red out of my 3 Super Red arowana. But i dont believe that is true.
As you can see in the FTR pic. it already tasted the lower fin of the GG
The Nan lights cost about 250$ each. but if you like the redish spectrum you can alway get some T5 or T8 that they use for plants and terrarium they are much cheaper
No 250$ for bulb and waterproof housing some people put it in the tank i used to but one of my SR was really bothered by it and it made him swim a bit tilted ( weird stuff ) plus when you put it in water it raises temp. not good for summer
I kinda agree that the GG is throwing things off a lil visually... Not that I would get rid of it! Your aro's will grow in just fine + the FRT, everything will look balanced again in the future and you'll have an awesome GG!
