what is the hardiest fish?

[ahloy]

thinking of setting up a very very low tech tank...

what is the hardiest fish that can survive in bare min condition.. no pump only plants.. but with regular water change..

the only fauna i can think of is betta.. any bro got other ideas?

[Enoran]

I think Coolie Loach, have seen them live in less than ideal conditions.

[scarnhost]

I still think they need some forms of filtration to keep water conditions up as they are susceptible to bacterial and fungal infections.

my platy are quite hardy. you could consider them. endlers too i have seen people keep in tanks with only plants

[Asgard]

White Cloud Mountain Minnows, Rhinogobius duospilus
don't need heater, can survive in poluted water

[Jervis]

It's important to place the tank in a well ventilated room then... I think Betta is a good choice

[Czyne]

I have seen a trichogaster trichopterus live in a bowl with no plants or filtration before. Had been in there for months according to the owner. It might've been able to live most of its life out in there if they hadn't given it to me to provide better quarters.

Feeder Guppies.

Feeder Guppies.

y feeder guppies?

[ludao]

I have collected some nice feeder guppies from my friend. The feeder guppies are quite hardy.. Able to live under straight tap water,in low oxygenated waters..

But i agree that bettas are hardy too They were my first pet fish.

[YamaMuthu]

I always thought feeder guppies are meant to be eaten fast and thus "made" to have a "short shelf life"?

My dad's feeder guppies never seem to survive long, but he kept buying them as they are cheaper. Economic downturn...

[ludao]

I thought so too.. My feeder guppies have lived for 2 weeks [since the time i got it]!

[Ingwe]

pleco! they're very hardy

[NingNing]

i vote... japanese fish.

[beetroot]

what is a japanese fish? koi??

[zoggin eck]

You didn't say what size tank?

If there is swimming room for many small fish, I would say White clouds - Tanichthys albonubes

Even easier, medakas - Oryzias latipes

Or if you want a single characterful fish, paradise fish - Macropodus opercularis
