Fish For 54Litre Tank

Mine have never looked as though they have ich - do any of the three species you have show this more than the others?

Seems across the board, but in less than half of the fish. I also have a 4th species which could be b.maculatus or b.naevus - quite pretty. I am still undecided if it is ich or not. If so it will be my first outbreak in almost 2 decades. I have found plenty of pics that look like my fish
Here is one example of b.uropthalmoides.

That looks just like mine. I have 3 left from the shoal I got several years ago.

If in doubt I would raise the temp for a couple of weeks, as you are doing.

Mine were all B. urophthalmoides, going by the descriptions on Seriously Fish. None were red, all had the black spot at the base of the tail, and an orange line above the black line. It's always hard to tell in shops as the fish look washed out but they never turned red which is what made me check up.

Off topic, I'm sorry - but I'm sure I saw you mention recently that there's another species that looks a lot like a harlequin rasbora, that sometimes gets mixed up with them and someone might have one in their school of harlequins? But I can't find that now, and I might have mixed things up when I was feverish! Do you know what I'm talking about? Only my dad's tank has five harlequins, but one of them looks different. At first I thought maybe a juvenile, but it hasn't changed over a year, it just looks a lot like a harlequin, maybe a little more slight, slightly thinner pattern. Made me wonder about that one. But I might have misremembered and it was someone else talking about another species even.

What a gorgeous little fish! It almost looks as though it's been sprinkled with a fine glitter.

It was me. Someone posted a photo of a group of harlequins with one that didn't lok quite right.
There are two species which look like harlequins, Trigonostigma hengeli (hengels rasbora, copper rasbora) and T. espei (espe's rasbora, slender rasbora, lambchop rasbora). You find them both on Seriously Fish.

I have T espei

Ah brilliant, it wasn't a fever dream, thank you! This odd one out doesn't look like the copper rasbora, but it could well be the T espei! The lambchop shape is thinner than on the harlequins, and it does have more red on the body than the others. I'll try to get a photo of it sometime. Thank you kindly! Might have solved an odd little mystery. So they sometimes get mixed up with harlequins and sold that way? Since that's how we ended up with this one. I can see how they get mixed up, but he also stands out as different from the others too.
