[Bolivian ram sexing]

Well the eggs survived the night with both rams continuing to protect the area. I think I can see two colourations, some white and fuzzy, with some tan coloured ones. Curious to see what comes of it.

My fertile ram eggs stay clear. The white ones were infertile.  Here is a photo of one of my batches 

How far along would you say the eggs in your photo are, in the tan eggs I have I feel like I can see one black speck but no where near as developed as what you have here.

I would say… no, not common. Were the eggs laid tan or white? 

I would have said tan, though looking right now they appear more white, might be the blue light of the night light though. Here's an image of the clutch right now. I watched the larger of the pair lay this whole clutch and didn't see the other (imaged ram) go to fertilize, or at least not right on the eggs from what I could see. Which started my suspicion they could both be females instead. Another image of the ram, can see the tail fin which does have somewhat long points to it, one of the reasons I originally thought it was male. Kinda blurry though

Here’s an interesting page on the general question.

My initial guess here is female. B-Rams are tricky.

Hmm yeah the egg tube is large and looks similar between the two. Is it common for a female to lay a clutch of eggs with no male partner? And for two females to prepare and protect the egg clutch? 

[Bolivian ram sexing]

Could anyone venture a guess as to the sex of this bolivian ram. I've got two bolivian rams in this tank and was 99% sure I had two males. That is until this morning when I woke up to them laying a clutch of eggs on a rock at the bottom of the aquarium. I've watched Lowell's labs video on them as well as a few pictures guides and I was pretty confident they were both males. Oddly enough of the pair their is one bigger fish and one smaller, but it's the bigger ram that is currently laying the eggs, the (second clutch today!). I've now lost all confidence In my sexing abilities and come to all you good folks. I haven't seen this guy fertilize the eggs yet so I'm starting to wonder if they are both females? Although the both seem to act protective of the egg clutch which I don't imagine a competeting female would do? Any help is appreciated 

[Removing glass divider]

Depending on how the divider was cut you might have an issue with the glass itself being bent or deformed in some way.

The divider was a little smaller than the width of the tank so there was limited glass to glass contact, the most mark seems to be where the actual caulking touched the glass. It's hard to tell by touch but I assumed the mark is a raised surface. Would the caulking actually etch into the glass? 

[Removing glass divider]

Hey everybody, recently got a used 40 breeder tank that the previous owner had put a glass divider in. I've removed the divider and cleaned up the tank with a vinegar water mix and gotten it looking pretty good. However the caulking for the glass divider has left two visible lines down the aquarium glass and it seems no amount of vinegar scrubbing or razor blade will clean it up. At this point I'm wondering it it's actually etched into the glass rather than a stain as It just doesn't seem to come out after hours of scrubbing. Anyone here dealt with this and have some tips? It's a little hard to see in the picture, I'm sure the average viewer of the tank won't even notice but because I know its there I'm pretty sure it's all I'll be able to see once it's set up haha.
