Thanks all
In the first photo, in addition to the 3 loaches in the photo, there are two more Red Tail Sand Loaches and 3 Horseface Loaches.
The Horsefaces are always buried in the sand, but I do see them at feeding time
There is also a school of 13 Cardinal Tetras.
In the "Blue Gravel 100 Gallon Tank" I have 5 clown loaches, 1 yoyo, 1 Histrionica, 3 Berdmorei, 1 Orange Fin Blue Botia and a Beauforti Loach.
The rest of the fish are South Americans like Severums and Tetras. There are two species of large barbs, some Parkinsoni Rainbows as well as several dwarf plecos.
I have two more Clown Loaches in a tank with 2 species of Geophagus eartheaters, 6 Bleeding Heart Tetras, a long fin albino bristlenose pleco and a regular brown one.
The 7 Dwarf Chain loaches are in a tank with 7 species of Barbs and 2 species of Danios, they are the only loaches in that tank.
I have another community tank with a yoyo, a kubotai and 2 Striata Loaches ... I think there are some Kuhli Loaches in there too but I have not seen them for some months now ...
I will try to get some more photos over the next few weeks
Some year, I would like to setup a hillstream tank
