Cohabitating GALS: safe or not?

[Rapps]

So there's a girl I follow on instagram and she had a pretty strongly worded post about how you should never let GALS cohabitate with one another because the different species have different needs and it can be dangerous to their health.

However, I would have thought that as long as the species you keep together like the same humidity and close to the same temperatures it would be fine to house them together.

What do you think? Have you housed different species together? Do you think it's risky? I'm curious to hear opinions on the matter.

I don't have any GALS species (USA member), but I've read some info about the various species on this site and other sites just to know a bit about them. Like you, I would think there are some that can be kept together if the habitat preference is very similar like you mention. Another thing I've seen discussed on FB groups is the fact that certain GALS have the ability to hybridize with each other and that it should be avoided in the hobby so that future GALS will not be "mutts" with questionable genetics. I believe there is a matrix somewhere showing which GALS can hybridize and which cannot...
I have also heard the converse, that letting different i.e. fulica morphs hybridize will lead to stronger future generations since there has been a lot of inbreeding with captive snails, although they can no longer be named "i.e. Jadatzi" they have to be named what hybrid they are.

I do keep most of my snails separated though, mainly to prevent problems with disease or pests. I have wild caught snails from various road trips in my area, so the potential of introducing some nasty parasite or mites is higher that people buying captive bred snails. Also giving each group a separate terrarium is good for breeding, since over-crowded conditions will mean your snails are less likely to produce eggs. Even if you aren't interested in having your snails breed it is still good to give them the most room possible, since if they feel too crowded they can sometimes secrete chemicals in their slime to cull the population back down to a lower more comfortable level.

Keeping different morphs of fulicas together really isn't an issue unless you're looking to breed and don't want hybrids. Theoretically, crossing strains should lead to stronger offspring by reducing inbreeding but it does depend very heavily on what individual genes each parent possesses.

I've seen different things from different people about keeping different species together, but from personal experience my reticulata seems to be thriving alongside my fulicas.

Thanks for the opinions guys! If you don't intend to breed your snails and all the eggs are going to be culled anyway though, breeding isn't really a factor.
