I can't do another neo since I already have a berried blue pearl which is going to release her eggs any time now. I thought about babaultis but my dumb FSS holds my pH at 6.4. It's gonna stay like that for a while now. :/ Also I heard the exact opposite about the wood; I read that it doesn't rot. If it does then I think I'll try manzy.
I've had 4 pcs of mopani before I switched, idk if it was rot but the smell was putrid. One smelled bad but didn't visibly affect my shrimp. Another started growing this hair, apparently some kind of bacteria feeding on fungus or fungus feeding on the bacteria which was feeding on the sap. Either way it was nasty lol. Eventually malaysian was the better choice for me but if it dont look nasty then I guess why change it.
You could get another neo and just scoop out the pearl babies, or if the pearl mama drops the eggs, which is quite common on the first batches, then you can get another type.
However some that won't interbreed but will breed in freshwater:
1) Babaulti- I have em at ph 6.5 with no issues, probably not as a prolific breeder as a high pH, but I didn't seem to have much luck with tons of babies in either.
3) Malayas- a larvae stage breeder that reproduces in freshwater, though I havne't seen any for sale anywhere
4) Blue Bee- It's a paracaridina, however I think the blues are a bit repetitive with OEBT
