I wanted to put both Hemiancistrus subviridis and Rio Xingu pleco, luckily their biotopes are completely similar. Here are two examples, same type of rock. https://www.planetcatfish.com/common/im ... e_id=11290 https://www.planetcatfish.com/common/im ... e_id=16465
It was important to choose the right rock, I'm not a geologist, but being a mountaineer, I've been lucky enough to see so much rock in my life. Looking at photos and videos of Rio Xingu it was not difficult to understand what kind of rock was present there. Luckily in the mountains around where I live they are made of rock of that type and so it was not a problem to go and collect some for my aquarium.
I managed to create a large number of dens by placing rocks of all sizes and shapes, but to give even more choices, lately I have also added artificial caves, well hidden with wood, as explained in this thread. viewtopic.php?t=51384
However, I have very rarely seen my plecs enter it, they certainly prefer natural rock caves.
I started the aquarium on July 21, 2022 so it is about six months old now.
The plants are not present in the biotope, but I need them to manage pollutants more easily.
66 gallons /250 litres
I change 10% of water a week to plain tap water
PH 6.5
NO2 0
NO3 25
KH 3
I have a lot of current, about 32 times the volume of water per hour (8,200 liters per hour).
I feed my fish mainly with peas, courgettes, carrots, potatoes and other vegetables, then also worms, shrimp pieces, tabs and food granules.
The main attraction is Hemiancistrus subviridis, it is 100% active during the day, while at night it goes to sleep in its cave. I am very lucky, watching it graze among the rocks is really what I dreamed of when I designed this aquarium. I can't wait to find other specimens to make a group of them. His home
