The last 4" nigers I got looked like this. In terms of color/pattern. I am going to have to net up and get a close look. I didnt look at the fish too closely. They were labeled as Turushuki Catfish. That is another name for nigers. This lfs always has the Turushuki Catfish in and I have always seen the nigers. Never the mouse catfish. So I didnt even look close. The one guy moved the sponge and they scattered like roaches. The glances I took I said "the 2 biggest". Then continued talking to the owner as the worker bagged up the fish.
Idk how I feel if they do turn out to be the mouse cats point closer inspection. I like almost any cat but Idk if I have a tank for small cats. The smallest/general size of the cats I am planing to keep is 2'. I have a tig, achara, these 2 and just impulse bought a nice looking jurunese tonight..lol... Plan to have an Irwani and a few others.
