Common Coldwater Fish?

Guys im looking into setting up a 4ft without a heater. Apart from goldfish, what are my other options? considering that durban climate isnt very cold

 

Nothing legal :blink1:

 

Guppies, swords,platties, white clouds, some of your barbs, hillsteam loaches, Myxocyprinus asiaticus etc etc etc

 

Koi?
platys and guppys will survive defnitly, ive got a friend thats even got angels in a unheated tank, maybe u should try and experiment....

barbel will defnitley make it.....but maybe not the other fish with it.

 

Koi is bred to be viewed from above and thus look pretty crappy from the side. with a TL of close to 1M a 1.2 will be WAY to small... i wont even put my biggest koi in my 2.5x80x90 tank....

 

i've read that Myxocyprinus asiaticus grows very large, do you think a 4ft will be sufficient?
also is it ethicaly correct to keep a koi in a fishtank?

 

i am yet to see one over 25cm... they grow EXTREMELY slowly - but yes they would have to go into a pond at a later stage. I believe they go black in adulthood

 

i had no idea that the hi-fin is a cold water fish, you only ever see it in heated tanks in the petshop.

Guess its a choice between the hi-fin and a common pleco, any thoughts on whether the pleco will thrive in coldwater?

 

Hi-fin-doll oach - not hifin pleco.....

a pleco will be fine in cold water if you add it in summer and let it adjust to the cooler winter

common pleco that is

 

bass?

 

illegal to transport of keep alive after you catch it. current sportfishing regulations set by DEAT states that you need to kill them if you catch them. same with the sunfish

 

Tialpia - Bream - Kurper - See IQ10000 thread

 

also illegal Zaf. the native species may not be kept/transported without a permit and the invasive species must be killed if you catch them

 

Stun them so they look dead

Yes I know illegal but I thought we were going through coldwater fish

he wanted cold water fish that he can keep in an unheated tank....

 

True - Tilapia fits the bill - just put the tank in the Okavango

 

are you saying that the tilapia is a coldwater fish? if so, i believe i've seen this fish breed in tropical conditions??? (reference to herotilapia multispinosa(blacklisted?!), or is this a different fish altogether?)

 

Yeah Bass they look awesome in a tank had a few a while back but u think O's is messy then u should see these guys but its awesome to see these guys take a small mouse

 

mmmm i dont think the Dam manager at potch dam will be very pleased with me if i start netting some bass fry for my new 250L :smile1:

 

the dam manager in potch by law should force you to kill them
