Yeh I think researching is half the fun sometimes, plus theres no excuse not to these days. They are living organisms afterall and best to give them their best opportunity considering they're imprisoned away from their natural habitat!
I have considered cloud minnows, but I've been battling with the other half and kids who just want a big fat centre piece fish such as a gold fish...
I think a good sized shoal/school of barbs should convince them otherwise.
For some curious reason, I added 20 cherry shrimp today, never had then before and I love them. And I know theyre not going to last long if I had 20 barb. So yeh.. its probably going to be a last minute decision on cloud minnows or odessa barb. (I have seen gold barbs in the lfs, and i think the potential size of them put me off a bit). Plus, the pics ive seen of Odessa's look amazing (havent seen them in real life yet).
im waiting for my anacharis to grow out a bit more and form a bit of a canopy as its currently too bright for barbs
