I looked into the fish/inverts you mentioned, and while I would absolutely enjoy taking care of each of them, I'm not sure I should try my hand at shrimp just yet. I'm still pretty new at this, and they sound pretty fragile. Honey gouramis are beautiful fish, by the way; I'm glad you mentioned them. I'll be acquiring a new 10g shortly; perhaps I'll home one or two.
Well, I researched a bit and happened upon the dwarf puffers. They're pretty interesting little guys. They sound like they're a fish that requires someone with a bit more experience than what I have, however. As always, it seems like there's a good bit of disagreement in the fishkeeping community about their minimum tank size, so I'm not really sure what to do, there. While I would certainly devote the aforementioned 10g to the single puffer if a 5g is going to cause stress, I'm not sure that would be the best use of resources. (I'm not intending to pick one up now or anything; I just like to plan for these things.)
I can't decide whether I'd rather prepare for a DP or a male betta. I know both are unique and (relatively) intelligent fish, so I'm kind of caught in the middle.
Any input/advice is certainly welcome.
Thanks.
