Normally I would say get whatever fish you like, but I worry about you getting very attached... unfortunately with aquariums, they are little ecosystems that can crash very easily and sometimes just crash and it's not even your fault at all. And a lot of the time, fish are bred for money in the hobby, so the health is very bad. I would just advice you to be careful to not put your heart on the line with fish, where as something like a dog can be taken to the vet-losing fish to disease or water shifts is a bit expected and you can't really take them to a vet... So maybe be careful, okay? Start with some plants? Or a cute snail?
Suckerfish are okay, but maybe more intermediate. Unless you want to start with a large tank, because most suckerfish will grow quite large and are very messy fish once adults.
As for the tetras, it just depends on what kind you get. Chili Rasbora and the tetras I have only grow to about 3/4 of an inch long! They are so tiny, and cute! And as long as they have enough room, and enough in their school-like 6 or more, they usually are fine and will display normal behavior.>>1145797
I love it when I have those days, but those tend to be 'good' days for me, where I'm already being productive and on it. Otherwise it's...fun. yea. We'll just call it fun.
I don't know what it is, I want to zone out. I know I can because I've done it before, but some days I just can't no matter how much I try, or I'll quickly get really REALLY tired, even if I wasn't two minutes ago.
