Thanks for the replies folks. I suspect these fish may be siblings, so can't assume a lot of genetic variation to start with. But it's good to know I should have a while before problems might crop up.

3 female, and 2 male endler/guppy hybrids have recently come under my care. My goal for the future is to have a sustainable, robust population. I don't mind whatever coloration or patterning they might produce. I have heard that I should introduce new genes periodically, but I'm afraid I might not be able to find endlers around here. These were the first I've found available near me. Question being: Would there be any problem introducing a guppy into the population at some point in the future? Also, any kind of tips for what to keep an eye out for, regarding genetic disorders would be appreciated. Thanks!

I've found pre-mixing equilibrium in a smaller quantity (large pot worth) of boiling water helps increase the solubility to the point that most all of it dissolves with some vigorous stirring, then I top up my container (20L cooler jug) with cold tap water, add pH buffer and dechlorinator, then put a small power head in, and let it circulate for a good while before using it. My largest tank is only 57L (flex15), so I can get away with just using a 5gallon water cooler for changes.

If it looks like a white film growing all over it, that might just be a colony of bacteria getting set up. Quite common for a new tank, and no worry, as far as I understand.

My first tank is just new, so no shrimplets yet. But, the blue neocaridinas I have in there just barge right through the school of lambchop rasboras when they feel like swimming to the other side of the tank. The rasboras don't seem to take any notice of the shrimp otherwise. There is also a school of boraras naevus in there, hiding amongst the plants. I fear they may predate on the shrimplets, considering where they seem to like to cruise around.
