My first betta reporting in

It's 8cm depth (actual should be 6cm perhaps considering the thick glass) is really small for a betta to swim let alone put in other things.

Most likely you'll have to remove your fish every time you want to clean something which may be stressful to it.

I have a 11cm ( ~10cm internal)) deep tank for guppy fries and that's kinda hard to work on as well.

The betta tank is an Up-Aqua super white glass 22x15x18 tank.

I'm located in Taipei

Beautiful

How long have you had ur betta?

Maybe still new not used to the environment yet I suppose.

Everyone got different approach but I use an azoo palm filter with wool on top and bio rings on the bottom as media. A cut pre-filter is used on the outlet to prevent disturbing the water which both fish and floating plant don't like.

Reason being is sometimes when I go on vacation or something, there won't be anyone to help maintain. Also my betta has a nasty habit of biting its own tail so have to take care of water to prevent infection.

The floating plants are there for the same reason.

You can don't use filter but have to be more careful and frequent with water change.

Speaking about water change, I do ~30% water change twice a week. The water I used are tap water de-clorinated with Seachem Prime and aged overnight.

So happens I was just doing some housekeeping so snap a few photos.

Just leave it. Its a sign that your betta is happy,healthy and looking for a mate.

Is the water getting slimy?

My 2 year + HM lost most of its colors di. Any idea why?

It seems healthy enough, eating well, bubble nest, active and all.
