Ok here it is. So far so good. Everyone has found own hideouts and its seems there is enough of them and its possible for the fish to go behind the background rock from both ends. The Garra does his "new-tank" jumping, hoping the glass holds. Temp is about 25C. The Sid's are behaving too. The Schistura balteata can now be seen even in daytime, which is nice.
Thanks for the compliments. The background is Aquarock background, superb in that way that it doesn't float. I like it the natural look in tanks.
There are Gastros (don't know how many), 4 Sewellias (adults), 7 Rosy loaches, 1 Garra flavatra, ~20 Pseudomugils, 13 Sids, 2 S. balteata. Everyone get they're share of the food, dropped at several places. And the hillstreams are the first ones at the dinner table usually. They can always eat some algae for dessert. Also Shrimps and Assassin snails, trying to have some MTS for the sand but the Assassins keep eating them.
I was worried about the combination but so far so good, no aggression shown from anyone, no bite-marks or eye-losses. Only aggression shown is between hillstreams competing for rocks.
