For your stocking Larkspur you could consider
- 1 female betta
- 4 guppies (2m 2f)
- 2 platy (1m 1f)
- 1 albino BN
- 6 peppered cory - like the loaches cories need to be in groups usually bigger than loaches, if it were me I would stick to 12 of your peppered but if you would rather have two groups of 6 you will still be able to have an other 6 but stick to the smaller species like panda and avoid things like your brochis etc.
- 5 chain loaches
For now I would leave it at that, if your taking on some fry and you have both genders of livebearers you will quickly gather numbers in your guppies and platies it also allows you to get your impulse guppies but not too many

Only thing perhaps to consider once the tank has matured further is maybe more female bettas to make a sorority but that might push your stocking a little.
