Fish don't get more nano than recently hatched ones. Here are three I just took photos of (baby pictures, awwww) in the fishroom. First up, MIcroctenopoma congicum, a couple of weeks old. Second - Pristella maxillariis tetras, under 3 weeks and growing well. Finally, a couple of days old...

I saw something last night that reminded me of past experiences fishwatching - a mystery fry. I know what it is and where it came from, but it's still interesting. Here's the story... I tried to breed pencilfish, Nanostomus beckfordi, a few weeks ago. After it didn't work, I left the tank...

Where you are, you should have at least two distinct species of Fundulus killifish (heteroclitus as well as diaphanous), with the possibility of a third if you are south enough. F. diaphanous, the banded killie is pure freshwater (the other likes some salt). I have never seen them anywhere but...

Last night, we relaunched the local aquarium club, with a turnout twice what we had expected, and a really fun auction.So in an era when aquarium clubs are closing or have very elderly memberships, here's one with members in their 20s mixed with older people, and an apparent real energy. There's...

A fan or especially ice cubes would be a lifelong chore in a hot country. Here in Canada, I've managed tanks in heat waves, where conditions were bad for a week or two. But over a year, that kind of heat would be deadly for a lot of fish. With that tank in Singapore, I'd be researching what...

I think spoken word poetry has evolved, and often poets are songwriters. Some even have singing voices. I used to write songs for a defunct band that never recorded (clearly, not the best songs), but every rhythm had to be just right, while not going away from the meaning I wanted to express...

I admire that really meticulous approach. That's planning! Tetra breeding is a bit of a lost art, and I hope it becomes more common. Back in the day, the older aquarists I knew almost all bred tetras, because it was an affordable way to have the large groups these fish look best in. That fell...

Is the problem on the underwater roots, or the leaves? I have the same plants here, but the leaves never show moisture. I get my water movement from extra power filters though, and not by airstones or bubblewands. The latter really increase humidity around the tank as the bubbles burst at the...

You might reduce the heat a bit by getting the tank out of the sunlight, but that is a brutal level of heat longterm.

I find if I put mine at the edge of the light, in a flow, it stretches out and grows really well. When it wants to, it can grow quickly, but it's a moody one. I started with one small rhizome in the early 1990s, and it's still going strong in a number of tanks. It's a beautiful plant.

We've drifted far from the point @JuiceBox52 raised. I used to play on a ball team where to be on the 'roster', you had to be a published poet, fiction writer or screenwriter. We would go to a restaurant/bar after the games - your basic rough place poet's hangout. There was always one, moving...

I get this a lot in my tanks. What kind of backing do you have on the tanks? Is the glass wide open into the room? Fish hide a lot in tanks with the back not covered here. I have some species that always hide until I have been in the room for a minute or two. When I enter, they take cover. But...

Also, you mentioned you check the water weekly. If you want to decrease problems don't check - change. I find my Corys do best if I change 30% or more of the water every single week, without fail.

Glass surfing is a stress response. Either the tank is set up wrongly for his species, or he's losing out in conflicts with other fish. It's also possible the tank is brand new and he's having difficulties with that. More info would probably get more help.

A drawn out cycling process is not the worst thing. I doubt you're in a hurry. You said your Dad did a lot of the maintenance, water changes etc with your small tank, so he may want to take it easy because it's a large task he's taking on. He may not want to get involved with plants at this...

Everything points to a bacterial infection, internally. Beyond that, you'll likely never know.

I used to buy small containers of blackworms to feed all my medium sized dwarf cichlids. I suspect they'd be big for endlers. Beware though, they tend to trigger breeding and its accompanying behaviours. They aren't tubifex, a whole other issue.

I have a non traditional sort of diabetes - not type one but not directly type two. I had trouble with really sugary treats for decades but passed every diabetes test. I had occasional symptoms of high sugar, but wasn't considered diabetic. It was the same for people in the older generation of...

Diabetes is another... so much for cake here.

When a jumping spider gets on a plane, does it have a parachute?

They look to me like Fundulus diaphanous, the barred killifish. Check them against pictures for the species online.

You can direct krib digging. In general, they are doing it to create nests, so setting up nest areas that need to be dug out will channel the behaviour. Take a coconut shell, cut it in half, notch a 2cm by 2 cm door in it and place it on the sand, and they'll go to work improving it. They are...

One type of fry warms your heart, another type of fry stops it. I'll stick with the fish type over McDonalds' anytime. Watching kribs care for their fry is a wonderful show.

I have never seen a Betta bite its tail. I have seen Bettas kept in cups and raised in jars tear their fin membranes once you give them good enough conditions they can swim for the first time since they were sexable. Farms protect those fins because ragged Bettas don't sell, but oversized fancy...

It always seems that when anyone asks if they can add more fish (and that includes me, inside my head), the answer is no. If you didn't have great misgivings, you wouldn't ask. We all hope someone will give us some grounded and realistic ideas on how we can add, but no such person exists. The...

Plants can choke each other out, and you need some space for fish. But dropsy is kidney failure. It is either the result of an internal infection, old age or a drop in water quality. As long as you're doing the needed weekly water changes and haven't introduced any new fish recently, it could...

I have known a number of people who started out with small bichirs with other fish, and ended up with large bichirs and sad memories. They are really "hot" now, and a lot of people love them. They don't linger in stores or wholesalers - the demand right now is huge. 20 years ago, they were a...

I'm guessing the beginning is ending...

When I have seen this, I have never seen it spread. The only thing that would is fish tb, and that would happen of the fish died in the tank and was scavenged. But that is not a likely cause.

Zero celsius again this morning, but the big moon makes it pleasant to walk the dog early anyway. Every morning now the ground is covered with a hard frost, though the forecast is for a couple of warmish days early next week. We've had a pattern going for a few years where south of us, in the...

A lot of things appear randomly in fish, as they do in us. A fish can have an internal growth, an injury or a disease that causes paralysis. It can be neurological, or not. The one thing that I have seen to be in common when this happens is the fish dies. I wish I could be more positive.

@anewbie - if you never get sick, you must be keeping yourself at the correct pH. But if you don't get sick, how can you get sick and tired? Sorry - it fit so neatly. I got both jabs today. My oldest daughter is a long haul covid person who got it before there was a vaccine. I have a tendency...

I had some rescue zebra finches ("They're old and will only live 6 months or less" the shelter volunteer said). In the years I had them, I realized they and crows are the only birds even I can outsing. Their Mommas must have been sitting in jails across the road from their Dads' cells if singing...

Nah, that's its short finned cousin who became a kind and gentle social worker. This other thing was blue with superlong filaments, which they destroyed on each other as soon as they met.

This is from the 9th century, by an unnamed Irish scribe in a monastery. His world might as well be another planet to a person in 2024, and yet I get where he's coming from. He's shared an idea I can feel. Poetry can have a lot of power when a skilled person uses it to communicate, even across...

This is an example of poetry that must be read out loud: When you're kissing with your honey, And your nose is getting runny, Don't think it's funny, Cause it'snot. You also see the elegance of shape in the poem, the way each line is shorter than the rest. Shape poetry was popular in the...

As @TwoTankAmin says, it's dominance behaviour. It isn't hunger. Not all Cichlids are as pecking order motivated as angels, and if you remove him to his own tank, there's no guarantee the problem would just shift along. My cupido when I had them didn't get like that. So that might solve the...
