Hi
@SueC lovely tank, that crypt is really nice.
I think the tank is too small for kuhlis as they need to be in groups and need plenty of cover to feel safe. They should be
shrimp safe though, they're not the best hunters. Unless they happen to fall mouth first on to food they're unlikely to get it.
Personally I'd add the shrimp, wait for the population to increase and then add fish. That way assuming you are feeding the fish they physically won't be able to make a significant dent in your shrimp numbers. I'm not suggesting over feeding but lining there stomach with a bread roll equivalent before you let them loose on the all you can eat shrimp buffet.
Slight thread highjack.… Rosie, where do you get them from? I never see them locally (planning a barrel pond outside).
The Bristol (Keynsham) MH had
Oryzias woworae a couple of months ago.
As already said, puffers shoal becasue it offers protection from predation.
I only kept pea puffers in a trio, as I like to try and breed the fish I keep, so can't comment on them being kept singly. Also I'm not an animal behaviourist or Dr Dolittle so can't be certain about how happy a fish is but in response to the above.
We keep other shoaling fish in groups for this reason. They shoal in the wild for protection and to make them feel secure. Although puffers seem to recognise people, they still have that natural fear of being predated, so keeping them in groups would help reduce this.
With regards to marine tobies, triggers, puffers and brackish puffers. It depends on the species. Some are found in shoals, others are solitary. Some come together to breed in large groups and some only in pairs.
I think the problem with puffers is that unlike other shoaling fish that sort out their hierarchical disputes without causing much damage, puffers are armed with a sharp beak and it doesn't take much to do serious damage with it. So it's easier to keep them singly to avoid disputes and harm to conspecifics. Whether that's a problem or the lesser of the two 'evils' I don't know.
I don't have dog(s) but worked in a kennel as a teenager. They certainly show different behaviour in groups. I wouldn't keep them in a tank though. Even though it looks like this guy does.
