Mono Sebae Update:
First, I love the name African Moonyfish, and I tell my friends that. Mono sebae sounds too much like a disease.
In the past 34 days the Monos have grown quickly taller and the mollies have grown fat. Some of the guppies have been eaten, but mostly spirulina and veggie diet for the Monos, which they love. The get Hikari Excel, TetraMin flakes, and Fluval sinking pellets, which mostly go to the Mollies.

I've been keeping the density at about 1.010 for well over a month will good reults. After I set up the new tank I will take them up to 1.020 and once I get everything settled in I will think about maybe putting in I really bright saltwater fish.
The current tank decor makes it easy for the Monos to hide, and they do it well, but school readily to eat.
I have purchased the largest tank that I can reasonably put on my hearth. This is 6 ft long and 125 gallons. That's a 30 standard on the stand & they are in a 30, so you can see the 4x difference in water. The current 7 gallon sump will be replaced with a 55 gallon sump.

32 gallons of water soon will become 160, so they should love it.
Right now I'm only doing one modest water change a week on this tank, where every other tank gets at least two per week. Once I go full SW, I will probably put them on a drip system.
But this will be a total Adventure being my first saltwater tank.
