Angelfish: An Experiment in Progress

[iam1ru12]

I read somewhere that Pterophyllum scalare and Pterophyllum altum do not breed.

Well, I have one of each in my 50gal tank and, by a stroke of luck, they turned out to be a pair, with the P. scalare male.

They have been laying eggs every three weeks or so, but I never paid any attention to that, knowing what I read before.

However, my curiosity got the better of me, particularly as the eggs laid last Sunday survived until today, Tuesday! So, I decided to take the eggs out (in a sword plant leaf) and transferred them to a fish bowl with water mixed with half a capsule of tetracycline, and aerated.

I'll just have to see what happens to these eggs.

Are the eggs fertile? Are you prepared to feed the fry?

Your "P. altum" looks like a P. scalare to me. No brown bars nor sharp indentation on its head to say it's a P. altum. How much did you pay for it? Breeding between both is possible.

:iagree: Altums have a distinct physical difference from Scalare.
your Altum appears to be Scalare.

do you have a better pic of the silver?

it could be a wild Scalare..

btw aeration and either methylene blue or hydrogen peroxide are used as anti fungal agents.. i would not use tetracycline

they are both scalare...altums have a much more tapered look to them.

sorry, i don't see an altum either. . .
