I have little aquarium - 60 litters, standard air pump, heater 100W, light 45 W, Substrate is gravel
My little cat fish likes to relax for around 30 min. after lunch. After that starts looking for more - maybe hungry again :)
And my two angel fish - I call them brothers. They often chase each other.
I now introduce my Yo-yo Loach. Quite often slipping like that :)
Well very useful fish. Cleans all the algae.
And closer look :)
