I just want to remind you that your tank is an inspiration to all of us
..
I wonder that maybe you could keep the tank with no ceiling
.you know....keep it all open like a big pond or a pool and maybe build a structure around it like a closed pool with acrylic walls, windows and a ceiling all around the pool space to keep the ideal temperature,and let all the sunlight enter with the option of controlling it with black sheets and maybe use a boat to feed the fish just like in a lake
.and also put some street lights around the pond to see at night
. im sure there will be some disadvantages like algae problems
.but it also would be nice
.you know
walk around the pool area
with some waterfalls
.
The 4 foot high wall that divides your tank really works to reduce aggression of the arapaimas? Or it only helps to reduce aggression of the fish that are on the bottom? If you could build it again would do you change anything of that wall? Maybe 2 foot high?
How big your arapaimas are and how old they are?
Anyway
..I just want to share with you the article I wrote about my 765 gal tank
...I hope you like it
