I started with one ten gallon and three female endlers and two male. That quickly grew into around 70 and since then I've been providing my local fish store with endlers. I now have a 20 gal and another ten gallon all with endlers.
This is my first 10 gal i havent changed much since I first set it up except for the addition of Co2. The male yellow tiger endler is the father to all the tiger endlers I have (including the orange tiger endlers in my 20 gal) and is the only remaining male out of the original two, the other was a black bar endler and has responsible for all my other black bar. I trim the algea every week during water changes but leave the rest of the algea for my two nerite and my endlers who feed on it all day.
This is my second aquarium that is also a 10 gal with a mix of yellow/orange endlers and black bar. These go to the pet store about every month and a half so it'll have its population reduced by 3/4 (they breedlike crazy). I have no clue what the plant is called that is growing out the top. I got it at petsmart but the label was missing and no one knew either.
Finally my 20 gal with six orange tiger endlers, one nerite snail, and four Amano shrimp. This like all my aquariums has Co2 and was the first one to be set up with it. It's been going for four months now and only recently got stocked. I have 12 female endlers coming into the pet store so I can keep the gene pool fresh. I also have a few pothos growing out of the top of this tank, trying to get a good set of vines going.
