@jwcarlson @Colu thank you for all the info
i didn’t feed at sunrise and found him on the evening swimming (looks more like he’s floating) sideways, i though there is something wrong with his swim bladder, i had to get out and my fear was to come back and find him dead and that’s exactly what happened 😢
I liked having a fish but if I’m doing it again I’m doing it right so if you have a forum explaining everything for beginners like a starters-kit i would love to check it out
thank for the help again.
