Pelvicachromis taeniatus Nigerian Red

As some may know, I had some difficulty piecing together a pair of these....but I've finally got a female that hasn't died on me.....and a female that is really a female. Yes, I know....the devil is in the details, right? Having fish that are alive alive and having both a male and female are quite prerequisite to spawning.

So, I've got a reverse trio (2M, 1F) in a 15 gallon tank, tons of driftwood, and water sprite. It's so dim in this tank, I have to get my flashlight to see what's going on. They've got choice of coconut huts. Other tank companions are a few clown plecos growing out. I was concerned about them competing with the Plecos for caves, but the Plecos can't fit into the coconut huts, and although the Pelvicachromis do go into the pleco caves occasionally, it seems to be a transient thing.

Anyhow, last night I noticed both males on their own and no sign of the female (normally, one is ALWAYS escorting her somewhere). Worried that I had lost another female, I started searching with the flashlight.....and there she was, guarding a whole batch of wigglers in a coconut hut! So, hopefully, this batch will make it, but I have two concerns......first, it's her first brood so her mothering skills are as of yet unproven.....second, their last waterchange had more tap water in it than usual ( they normally get RO cut with tap water) and I've been letting my tanks cool a little, so between these two factors, I'm likely going to get a skewed M to F ratio in the fry.

But, anyhow, I'm glad that spawning was on their minds, and I'll post pics as soon as I can when she's got the fry out and about.

Congrats! Shawn is right, however. The club should just rename the BAP the chriscoli breeding program.

Congrats! With your luck finding and keeping females alive, maybe you'd be better off if your ratio is skewed in the female direction :)!

I know with the D. macs there is some evidence of skewed ratios in the wild (more females) which makes sense, since the males don't help parent. Some have had one male spawn with several females in one tank within a few days. It doesn't sound like your males were helping your lady out with the brood - are these guys similar?

Update?

How are they doing? Inquiring minds want to know.

On the M/F ratio, the literature I find is a little scattered, so I'm not certain whether temperature or pH is more important and which way they skew the ratio. According to an article by Albert So, high temp means more males, so I'll go with that.

On my Taeniatus "Lobe" fry, the temperature was probably around 78 and the pH around 6 (not so sure on this) when they were conceived and hatched. Now, looking at the juvies, which are nearly an inch long, I see that a few have the long horizontal stripe, but most do not. This could simply mean that a few have matured enough to show the stripe, or it could mean that I have 90% males.

Fry are still doing well! Mom and Dad have been leading the gaggle around the tank. I was also inspired me to get my brine shrimp hatchery set up....the fry seem to be really enjoying them. I've been alternating the brine shrimp with golden pearls between batches.

That tank is probably in the 76 to 78 degree range. pH would have been in the ballpark of 7.6 but might have been lower due to the large amount of wood in the tank.

On my Moliwe fry, the only early indicator of gender that I've found reliable is the appearance of the spot on the female's dorsal fin. Do the Lobe have that spot, too? I've also found that raising them on a light colored substrate makes that spot really hard to see early on!

She's got a spot on her dorsal fin and another on her caudal.

I've got them on a light colored sand substrate. Excuse the photo quality, with an iPhone and dirty glass:

Gotcha. When I see that spot showing up on the juvies.....I know I've got a girl. If there's no spot, I wait to assume its a male, but usually you can see some differences in fin shape in the males when you have a confirmed female to compare them to.

She looks good in your picture, Matt!

She's quite striking. I think she's ready to go again, so am thinking about moving the juvies this weekend, and seeing if they'll span again.

It may be time to move the parents out of the tank.

Mom is splitting her time now between flirting with the 3rd-wheel male in the tank and the fry.

Here's a pic of the trio of adults in the tank:
