Have you been able to observe any interactions between the two Pangio species? I've heard mixed things, namely that they don't socialize. Just curious about your experience.
I don't think I've seen enough of them to really make a call but it seems about 50/50 right now. They will all bump into each other in typical loachy fashion. Sometimes the stripys follow the browns and sometimes they both ignore each other. One thing I haven't seen is them all resting together in tight hidey spots. They all rest together behind the L shaped driftwood, tho. I think only time will tell.
So video. I ended up taking about a 5 minute video tonight which will take probably the whole night to upload to youtube. But it's on the way! And all the new little loaches came out! So consider this a teaser.
