Epsom salt with fry in the tank?

[duanes]

Haven't kept them, so I can't speak from experience, but Bocourti natural habitat is somewhat variable and includes fairly hard, high pH waters, averaging 7.8 pH in one of their lakes. So I suspect they can handle some Epsom salt and it may be beneficial.

I add epsom salt to my Cyphotilapia kapampa tank every water change, including fry, and extra when a female is getting ready to spawn. In my water, limestone sourced, the kapampa do better with the added Epsom salt, for one thing it prevents the egg impaction they can be susceptible to. I've also been adding a little to SA tanks, which includes wild Aequidens, Heros, and plecos, and they continue to be quite happy.

Agree with this.
Lake Izabal (which is considered their "type locality), is heavily influenced by the incursion of the nearby sea, so the salinity and conductivity is quite high.
Both salt (NaCl) and Epsom salt (MgSO4) should be easily handled by bocourti.
De-shelled peas may also help the adults digestion, since they are primarily vegetarians.
They are known to graze off overhanging terrestrial vegetation in nature, so I fed mine everything from peas to dandelion greens (along with low in animal (fish) product proteins) like Algaemax.

I also grew hair algae on outdoor ponds to supplement the terrestrial veggies.
