Update:
So I was planning to get a new tank, add one more filter, and change around the scape but decided not to as the group keep breeding so there is tons, and I mean tons, of little fry on the sand. I have no clue how I am going to move them so no tank upgrade for them as of right now. I had everything planned out too.
I will be leaving for 5 to 6 months, come back for 2 months then leave again for 5 to 6 months so I think I will be able to move the offspring into their own tank to grow out, before selling, as I do not want them breeding with the parents. I don't plan to keep the offspring as I won't have time to care for another tank/more fish. I may add a filter though. Another 2215 if I get the chance so I can remove the powerhead. I did add an airstone today as the weather in CA is hot and the loaches looked like they needed it.
Saw about 5 spotted/white fry that are over .5cm. The rest are still young fry. Male has been breeding with the 3 females so far at least twice a week. I'm not sure about the other sewellia as it hasn't bred yet. Looks to be a female though. Trying to remove some RCS so the fry have a chance of survival while keeping the population down. Since removing the stiphodons, I have a bunch of daphnia and other small creatures in this tank. Nothing bad which is good.
Off topic: The notho group (2m/3f) have been trying to breed. Females are full of eggs but do not look interested in the males yet. I'm going to check the peat on their next WC to see if there are any eggs. It's their first try though so I don't expect a lot of eggs. Just setting them up to be ready for my mom to care after them.
