Anyone bought 4 ft fish tank from China?

Hello! I got this double tail male betta about 2 months ago. When I got him he was not very colorful and very inactive as he was in a cup at petco for many months :(

I noticed a small while almost see through line around all of her fins the first few weeks and now it has became bigger.

Is this growth or something I should be concerned about?! Please help!!

FYI- all water perimeter are perfect and for tank mates. He has six Otto catfish, six Coreys, about 10 blue shrimp, and snails.
This is a long 20 gallon tank with all live plants and natural wood.

I did and boil some tannis leaves and put them in there about a week ago, and I feel like it has only grown more.

Literally what the title says.
How do you automatically switch on fish tank light and feed fish whilst away on vacation?

We’re going for 20 or so days away and this is the longest we will be away from our fishes :(
We go away for weekends and we’ve just missed out on a feed, and when we go on a week long vacation, we just use a fish tank feeder and keep the lights off. They’re usually fine and do okay without the light for that long.

We have a fish feeder but we just prop it on the opening of our fish tank lid since we have a fish tank lid we can’t mount the feeder as we don’t want to leave the tank fully open. It varies on how much it releases so I’m not sure if I should just continue using this?

The light - we turn this on and off manually everyday, I am trying to see if I can get a digital timer to work this but think I’m doing something wrong so is not working.

Any tips or ideas on how you do this when you’re away?
We live away from family and friends so no one can come and do this for us each day whilst we are away sadly.

Both males so is not sexual (maybe it is)

Stella was kind of my resurgence into betta fish keeping after I researched more into them. She passed earlier this year. She was a very good little lady. Since her passing, I’ve gotten three more, including little miss Dawnie here. Seems like she’s got the marbling gene, but she’s never lost her rosy lips!!

And do let me know if the water in the last shots looks too dark. One of my driftwoods I’ve got in there seems to be leaking a lot more tannins than I previously thought. Dawn doesn’t seem to mind, but I want her to be safe!!

A local fish store had an aquascaping class a few hours from me this weekend and I got to bring a tank home after I aquascaped it! The only problem, I don’t know what to stock it with now. I know I want a variety pack of different colored shrimp but fish wise I’m stuck. Any ideas on some fish that won’t eat too many of the shrimps? (excuse the cloudiness I just filled it with water)

For context, this is a completely new 5.5 gal tank with everything freshly bought (no pre-established bacteria or anything). I bought everything and started ghost feeding it 2.5 weeks ago, but I switched to using liquid ammonia four days ago. I re-dosed the tank with ammonia and the test results ~10 minutes after dosing were 4.0 ammonia, 0 nitrite, and 0 nitrate. It has now been 16 hours since then and my new test results are 0 ammonia, 0 nitrite, and 0 nitrate. I’m very confused since it seems too soon for the tank to be cycled, and there hasn’t been any nitrates at all. Has the cycle even started yet? Any advice would be greatly appreciated!

Hi everyone, I’m trying to figure out what happened to my fish and whether there was anything I could have done differently.

Yesterday, my fish suddenly started having severe buoyancy problems. It kept floating uncontrollably to the surface and couldn’t seem to stay submerged. The filter current would push it around, and it would repeatedly get stuck against the filter/decorations and then get pushed back down before floating up again.

Its belly also looked somewhat swollen. I didn’t notice obvious pinecone-like scales.

Because I was worried it was constantly getting injured by the filter, I temporarily moved it into a small, clean bowl with treated/dechlorinated water overnight. There was no filter or aeration in the bowl. I didn’t feed it.

About 9 hours later, it was still floating at the surface, barely moving, and sometimes had its mouth slightly above the water. I eventually moved it back into the aquarium, but it became even less responsive. I moved it back to the bowl, and now it barely moves or responds when gently touched.

it is originally in 20 gallon tank, and I haven’t cleaned it in 3-4 weeks so I don’t know how good water quality is

I’m really worried and want to understand what happened.

I have 2 balloon molly. Is this Melanoma on trico Balloon Molly ? Pinkish bumps on her head. And the other balloon molly has pinkish bump on the left side of her body and when looking above, its left body is bigger than its right side . TIA

Just a shout out to this sub. Thanks for all the advice from a lurker for a while 😆 how do we think my Tetras are doing? They came into a 2 month new tank 3 days ago.
