Cleaning

I wouldn’t recommend hiring someone unless it’s a huge tank with monster related fish (as they may think you are food).

Most people clean their tanks once a month or twice a month depending on their water change schedules - and it really just involves taking a cloth and rubbing away any algae from the glass and decorations, using a gravel vacuum to suck up extra waste/uneaten food, and also making sure the water splashes that have dried on the lids and sides aren’t built up too much.

It is a pain, but it is a regular part of owning an aquarium, and I recommend learning to do it yourself.

I just use a rag, along with a sponge whenever I do water changes once a week or so.

I mostly just use a soft sponge to wipe the glass on the inside, and then maybe a gravel vacuum (if I have gravel) or using snails if I have sand to clean/mix all of that up.
