The male fertilizes the eggs while the female carries them in her pelvic fins, then she places them on the glass or plants.This might be a weird question when it come to egg layers but r catfish eggs fertilize when they r laid?
Ok that is what I wanted to know thank uThe male fertilizes the eggs while the female carries them in her pelvic fins, then she places them on the glass or plants.
But they are fertilized outside of the body if that is what you are asking, but they are fertilized before they are placed where the female wants them.
For corydoras anyways. Different catfish spawn many ways.
If you can get a view if them from above and the sides for both thatd be perfect, better able to sex them by girth or the dorsal fins with paleatus.2 new catfish not quite sure if they r females my wife believes they r
I thought same thing on sexes. I’m getting good, thanks to CassCats tutoring.First photo is a male, 2nd photo the rear cory is female, 3rd photo female, and 4th photo is a female paleatus (peppered) cory, not aeneus/bronze/green.
The paleatus has some fungus on the dorsal fin, looks like the barb was nipped or damaged, and has become infected.
Id suggest adding an Indian almond leaf directly to the tank to help heal that up
I got 4 green and 3 pepper so this will be funIf there's lots of chasing behaviour going on, that's likely pre-spawning behaviour Keep an eye out for eggs stuck to the glass!
They're most prone to spawning at dawn, when sunlight hits the tank, but not always. My bronzes recently spawned at 5pm, lol. Lazy guys!
You can encourage them to spawn by doing cooler water changes. Do a normal water change, but have the replacement water be a few degrees cooler than the tank temp. Replicates the cooler rainy season that they usually spawn in in the wild. Do those daily, with a batch of mature, mixed sex cories, and you'll almost certainly get some eggs
