That doesn't leave much room, except for substrate fish. The corys would work in here.
The Black Widow Tetra could be with the molly in a larger tank than a 29g, which might disuade them from fin nipping. With the present tanks and no larger planned, I would return these tetra.
The neons alone in the 10g is possible if you want to keep them; not what I would recommend from scratch, but as you have them... . Plus substrate fish, the otos in this case.
If I put all of my mollies in the 29 they will fight, this was the reason I originally got the 29 was to separate them. I would have to get more females wouldn't I? But then I would have more fry all the time.
The main concern is the mollies because they can't be in the same tank and the 10 is too small for them and I don't want more females because that will just give me more mollies...
As for the neons going in the 10 gallon by themselves that is a very good possibility if i keep them.
The black widows are going to have to go. I can take them back tonight.
I will move the two red wag platys into the 29 tonight as well.
So let's see what this would look like after I change it up
29 gallon tank:
11 Neon Tetras (still deciding if I want to return them or put them in the 10 gallon)
4 Bronze Cory Catfish (is 4 enough? I had 6 and 2 died)
2 Red Wag Platys
2 Creamsicle Mollies
2 Snails (babies)
10 Gallon tank:
Male and Female Black Mollies
8 or more baby snails
So if that is going to be what I am dealing with, I would need to return one or two of my male mollies so I could keep mollies period (in the 29) without fighting. This would leave me with a breeding pair of mollies.
I would have a lot of room left if I returned the neons, black widows and 2 male mollies.
I will soon have grown up baby mollies and platys, I could keep 1-2 female platys max to keep in the 29 and donate the rest (no further pregnancies)
I am also still thinking I want to keep my breeding pair of mollies or just stay with my pair or males. This is because I will have constant fry and no place to keep them.
I could wait until the mollie gives birth, give all my males away, keep like 2-3 maybe 4 female mollies. What fish could I stock in the 10 gallon with the ottos once I take all the fish out and fry out? And if I don't keep the neons.
Also what fish could I keep with the mollies, platys and corys in the 29?
I'm foreseeing 3-4 platys and 2-3 mollies depending on which route I go.
