How to sex sparkling gouramis
I am going to be getting 2 sparkling gouramis to finish off my 15 gal. tank.

Right now it has 6 cories and 1 male guppy (I separated him so that there would be no more mutant babies).

I have heard that the gouramis would be happiest with one male and one female. I have also heard that they are very hard to tell apart. Any advice on how I can do this, or will they be happy if I just randomly pick 2?

Also, kinda off topic but I think that my male guppy may be lonely. Will he be happier when I get the gouramis or should I pick him up a buddy or two while I'm at it. I know that this would make the stocking a little heavy, but the tank is planted and I am very strict about my weekly water changes.

At Your Local pet store, the staff should be able to pick you out a male and female. if this is not the case you might be out of luck. Males generally tend to upset eachother at times, and wont get along to great, although they wont kill eachother, there will be aggresion. I say two Females is the way to go.

About Your guppy, do not worry, he can live happily solitary, though one other female guppy would be a good thing to do. Don't worry he doesnt need this, so basically it comes down to you. i would get another, but no more ( unless you want a guppy community) If you don't want to spend the money DON'T he'll be fine. if you do however have the funds, get another.

I would do the research on sexing them yourself, as I certainly wouldn't count on the LFS staff being able to do it. On a recent trip to the best LFS in my area (in terms of prices, selection, health of fish sold, cleanliness of store, etc etc) the employee that helped me couldn't even sex Endler's livebearers, which are just about the most sexually dimorphic fish I can think of.

Thank you. I have looked up how to tell them apart, but it seems it would be difficult in a pet store where most fish are really stressed and not showing their colors. In this case I may just get one. Is it true that they don't mind being solitary?

Kind of off topic but...

I was thinking of moving the guppy back into the 10 gal with the other 4. They are all so tiny and well, genetically a mess, that I don't really think that they could have many babies anymore. And any that did make it would probably be eaten. So, with the guppy out of the way I thought maybe I would have room for a few oto cats to help with the algae. I have researched them and all I can find is that they like to be kept in small groups. Would 3 be good. Then my stocking would be:

-6 cory cats
-1-2 sparkling gouramis
-3 oto cats

Would this be too overstocked for a planted 15 gal that has 20% water changes every week? I could obviously up the water change percentage if necessary. Thanks.

That would be fine. You might even be able to increase the number of otos to 6 or so and be just fine. Keep in mind that feeding them can be difficult, so if they eat all of your algae you may have to supplement their diet with fresh veggies. The otos I've had would never touch any sort of prepared foods, although some people have reported getting them to eat algae wafers.

Thanks. I didn't think that it would be a problem especially since the plants are great at soaking up nitrates.

I've got plenty of algae for them, but on the off chance that they manage to eat it all I'll definitely supplement.

It's tricky when they're small, but males have a much pointier anal fin, whereas the female's is more rounded. Just look reeeally really close. If you let the LFS employee sex them, make he/she tell you *why* the fish are each gender so you know they're not just guessing.

If you are keeping the guppy separated for genetic reasons, leave him in isolation. There is no reason to allow breeding of bad genes.

Well, I was going to let them eat the babies. The only reason that I was going to put him back is because I heard that the sparkling gouramis would be aggressive toward him. Is this true?

Thanks for the advice on how I can tell them apart. Now I just need to find a store that sells them :-?.

Nah, other gourami can be aggressive, but sparkling gourami are about the most docile fish you can find. If anything, the guppies will stress the gourami with all their movement.
