what are the differences between irwini catfish, and niger catfish?

what are the general tank conditions and tankmates for them?
warm water, right?
my tank is pbass, TSN, and eventually an aro

i know someone selling a 6" irwini for 25 bucks, is this a good deal and comptible with my tank?

any good photos of either fish would be appreciated!!! thanks
 
thats a good deal
 
Hi,

niger gets without any problems double of the size which irwini commonly gets.
and it depends on the irwini if it is hiding allways or not, I had different ones.
Niger normally are very active but like I said they get huge and eat tons
 
are the ok with pbass and tsn and aros?

and when im looking at pictures, it looks like nigers are all black and irwini are 2 different colors? is that correct?
 
any good photos of either fish would be appreciated!!! thanks

thats a great looking fish!! how long have you had him, and whats / how much do you feed him?

The niger eats several pounds of market shrimp per week as well as sinking shrimp, veggie & spirulina pellets in between.
