Thanks Birger,
Maybe I hope that they are S. grandiops, they stay smaller than the multis

I would definitely be posting a picture just to see what I bought. I'll take a look after this post to make sure I don't buy anything that looks like these but grows into a monsterfish!
I can make the conditions whatever the chosen fish needs because the tank is only for them until they're happy and healthy. I already have a softer water tank running with rainwater/bottled springwater and some tap for minerals etc (?) okay for pictus
but my tap water is very hard and ph 7.4 on average so it would be okay for the synos, I think. My mineral content is so high in the tapwater that my heater in the
softwater tank looks like it's encased in stone! Think that would be too much lime/calcium even for the synos? Or is there anyway to reduce that before it goes into the tank?
I have a test for kh and gh but I've decided that I don't know what I'm doing with regards to that little test because the readings from one day to the next are always so different...It's not expired, it's just me.
Don't really care if they breed but that's always a bonus just to watch the goings-on.
How long could I keep 5 of any of these three in a 10 gal or is it the super-clean water that's really a larger concern here with such a small starter tank? The 33 gal will be in the works just after the 7th of July (big show$$

) but I can't cycle it fast enough whereas the 10 gal can just be hooked into the bigger tanks for now, hard or softwater.
Sorry for all the questions but thanks for the help!
Racing, shoes and fish. Nothing else matters. Oh, and bacon.
