I am thinking about putting a tank in to collect peppermint larva
They would have to go through a 4” drop though
Would they be able to handle that or are they too fragile ?

They'll be fine. My hatcher drops about that far in to my larval tanks. Just put the tube below the water level in your larval tank. Use a tee at the top to provide a vent, slow flow.

Another question I have 3 boggessi in a 20g Long
Just got 5 wurdemanni would it be ok to add them to the same tank ?
Or would they need there own tank ?

I'd put them in their own tank. There are some interesting interactions that occur between the two species and its best to rear larvae when you know what they are.

Reproductive isolation between two sympatric simultaneous hermaphroditic shrimp, Lysmata wurdemanni and L. boggessi *

Dong Zhang; Junda Lin; Joumlrg D. Hardegec; Andrew L. Rhyne

Abstract
To investigate pre- and post-zygotic isolation between two sympatric and phylogenetically related species of Lysmata shrimp, two assays were conducted in the laboratory: (1) no specific mate choice where mating between the two species was 'forced'; (2) specific mate choice or preference where a female had a choice between conspecific and heterospecifc males. Behavioural studies reveal that female L. wurdemanni accepted only conspecific male shrimp, whereas L. boggessi females would mate with an interspecific male if there was no conspecific male present. When males of both species were present, L. boggessi female always mated with the conspecific male. Male L. boggessi in general did not respond to the sex pheromones secreted by female L. wurdemanni and did not display any pre-copulatory behaviour to newly moulted female L. wurdemanni. On the other hand, some male L. wurdemanni responded to female L. boggessi. Although mating was successful between male L. wurdemanni and female L. boggessi, the resulting embryos lived at most for 10 days and failed to hatch. The results indicate that the two species are both pre-zygotically and post-zygotically isolated. Behavioural observation suggests that chemical cues are most likely responsible for pre-zygotic isolation.

Thanks
I kinda thought that they would be better off separate But better to be sure
Now just have to drill them some new 10g tanks
The boggessi prob wont be too happy there getting evicted and downgraded lol
