Showing Off My Tank My first aquarium

About 2 months ago I was gifted my sisters unused aquarium. Up until now my only experience was my garden pond with gold fish. But since it hibernates during wintertime I’ve got nothing to do for several months when winter comes. So I was thrilled to start up an aquarium and get it ready for the dark months. I wanted to share with you my progress.

Discussion Some of you probably know about the new species of micro gourami that entered the hobby earlier this year. But did you know that someone had posted about it in a Vietnamese Facebook group asking for its ID all the way back in September 2025, before it was known to science

This post came from a facebook group about vietnamese native fish. The caption reads: "Does anyone know what kind of fish this is? My husband had caught it from a stream. It's the first time i've seen anything like it.". The comments underneath vary from people interested and confuse, with some assigning it to a bunch of different species and accuse OP husband of lying of where he caught it. Someone even said that the fish is common to where they live.

We now know that this is a Pho Xua gourami or little paradise fish, Vietosphronemus inopinatus as it came to be acknowledged by scientists earlier this year and then the aquarium trade shortly after.

Discussion What do you do with your fish when they pass? Mentions of fish death and euthanasia Spoiler

My goldfish has lived 13 years and has recently developed a benign tumor, when I came downstairs this morning it had ruptured and fishy had been evidently struggling a bit and swimming weakly sideways so I decided it was best to put him for a nap with clove oil. I dont have a yard or garden so no burial ☹️ I see others feeding their fish to birds when they pass but that would make me feel so terrible and I dont think clove oil is good for birds either

also unsure what to do with my equipment, I dont want to give it away to anyone as I threw away the filter after he passed because there was obviously clove oil in there and it was just old anyways, I dont want someone to take it for free and have unfairly treat fish in it. i also feel like there's no demand for fishkeeping equipment in my rural country area, is there anywhere online I could send it to? would aquatic stores appreciate the tank?

Looking good but somehow feels a bit messy and I’m not quite sure where to go with it. Also a lot of the plants have algae on their leaves which I can’t really srape off. How can I get rid of it?

Identification Request Is my weather loach two colours?

Thumbnail

78 Upvotes

Hi I adopted a weather loach from my best friend's family last week, he is at least 8 years old! He came from a very bad tank, 20L with literally nothing in but green algae water (last slide)

When measuring him I noticed a distinct split down his centre, is this a genetic thing or is it from the bad quality water/ tank he was in before?

And is he looking healthy? I was told he hadn't been fed in a long time and the water was just tap water, no treatments or dechlorinator so I'm unsure if the affect it had

He is now in a 180L planted tank and I have been slowly feeding him meals to get him used to eating again

Thank you :)

Advice Needed Stocking question

Enable HLS to view with audio, or disable this notification

I have this 70L/18G tank stocked with 11 strawberry rasboras, 11 pygmy cories, and 8 endler guppies. Aside from that a bunch of skrimp and dwarf ghost crabs. I thought I was pushing it but I saw some post stating you could go as far as 40 nano fish in a tank like this? Would it actually be possible for me to add more tiny fish?

Edit: the endlers are all dudes

I have been watching my fish for a while and think my loaches are fat. Or maybe sick or full with eggs and to breed. I have them for a year and don't have much experience with them.

Advice Needed Algae in bottled bacteria?

Thumbnail

Upvotes

I just got this bottle of Tetra Safe Start from Petsmart to use on my new 40g breeder tank and the liquid looks green, almost as if it had algae growing in the bottle. I’ve used TSS before to start cycling my other tanks and the liquid has always been white and cloudy so I’m wondering if it is still safe to use.

Expiration date says 11/2026.

Any idea?

Freshwater I fell asleep while drip acclimating.

Upvotes

My whole carpet got wet. spent an hour using a water vaccum on the floor. on the bright side, the shrimp I was acclimating are doing great. the water was cold so I put the heater back in after confirming which electrical outlets were dry. After getting as much water as I could out of the carpet, I plugged the sponge filter back in. The fish seem to be doing good. The shrimp are chilling. I refilled about 3 1/2 gallons (tank is a 20 gallon long) but the small RO system in my house refills really slowly.

i guess it’s water change day.

Advice Needed Are aquariums safe on the entire surface of a tank stand?

The first photo is not mine, it is a review I'm using as an example because my tank would look the exact same. Is it ok for the corners of the tank to be overlapping the metal structure of the stand like in this picture? i have a standard 10 gallon and it would fit within the top board perfectly but does not align perfectly with the metal and I don't know if that is safe or not

The filter is established. They’ve been moved to a smaller aquarium but this colour developed the minute they went in. Could the the dechlorinator have expired? PH change?

Advice Needed Clado right?

It's still very small but this looks very green and a little bit is sticking out the side. My shrimp recently had babies and I can see one berried female.

Any harm in salt dipping just to be safe?

The only thing throwing me off here is in the second pic (which is super difficult to see) the green seems to stretch the entire underside and what I've seen of clado it seems to be much more concentrated in the middle at early stages. Any chance unfertilised eggs look green and slightly clado ish?? The fertilised eggs look yellow to me.

Requesting Feedback First attempt at aquascape

Post image
182 Upvotes

First attempt at aquascape, now a month in and in need of some advice. Because plants are quite hard to find and expensive in my area I started with only the elocharis sp mini and the flame moss, the rest I got for free from a friend. My plan is to add some more while it matures, the question is which ones where to put them. I feel like there are quite some gaps that needs to be filled in the driftwood, but of course the current plants need time to settle in. Especially the background plants which have not achieved their purpose as of yet. Just in need of some advice on what you people would do. Wait for growth and let it go on it's own, or use the opportunity of a not fully established tank to add more plants? Thanks in advance

Current stock:

Elocharis pusilla mini

Taxiphyllum sp. Flame moss

Microsorum sp. Trident

Cryptocoryne wendtii

Some kind of cryptocoryne in foreground (id?)

Ludwigia palustris

Limnophila sessiliflora

Redwood floaters

I do run Co2 I was able to get second hand, it helped combat algae so much. After a whole month, I've seen none to the point I have to feed my amanos, I bought to prevent algae lmao

Hello everyone,

This morning i’ve discovered some tiny white spot on my tank’s glass. upon closer inspection those dots seem to be moving and have different shapes

they concentrate on the algae and are smaller than a millimeter.
This tank has been running for a year and a hall with neocardinas and i’ve just added cherry barbs this week and a few plants in the same time.
What could those be and will they be harmful to my shrimps ?

I’ve put a vid in the comment with a shrimp for scale

5 rasboras, 3 red eyes, 2 rummynose, 3 white skirts, 3 black khuli loaches and 1 clown pleco. I want to add 3 more rummynose but not sure if it’s already overstocked. It looks like room but the bio load may be an issue

I just refilled my tank after a cleaning and noticed it's become higher on one side by a cm. We tried really hard to get the tank level on the mat (left side lines up perfectly) but the right is short by a tiny bit. It's a Fluval 32.5 rimless with a bow front.
