Have Duboisi and Moop fry growing out in a 10 gallon for now. Just got 3 more Duboisi spit yesterday. Can I keep all these together to grow out ? First 8 duboisi fry are 1 month @1inch, 3 moops are 1 week at 3/4 inch and these last 3 are yesterday about 1/2inch. There is a pretty big size difference from first batch to yesterdays. Safe to put together and can I keep adding fry as they spit.
