Guppy Population Control in 90L Tank

[PL1995]

I currently have a 90L tank with an ever-growing population of guppies. Unfortunately I don't know many other fish keepers and currently only have the one tank, so the only solution I feel like I'm left with is introducing a predator fish to help control the population.

I'm stuck for ideas of what would be best suited for the job, does anyone have any recommendations for an ideal candidate?

Small tank to add a predator. Another method into get rid of all females and just keep males.

What temperature and pH does the tank have?

A 90g with guppies has got to be LOT of guppies!

I started with 5 odd ball endlers and guppies in a 29g a few months ago. I've got a 29g and 10g loaded with them now.

I've culled a few deformed ones in my oscar and severum tank, which they gobble up instantly, aside from one lone female guppy in with them that's been there for weeks. She got in there from shared water change equipment as a fry. Smart bugger. She predicts their movements before they do! lol.

Look for a local fish club. There are some around most everywhere, and they usually have auctions at monthly meetings.

Thanks for your replies everyone - I keep the tank at 74F.

I'll try and find a local fish club - thanks for the suggestion!

When I say 'predator' I'm more interested in something that will go for the fry.

Perhaps going for another tank is the best option in the short term but I wasn't planning on getting another one just yet, oh well!

90 liters isn't really very big--there are lots of predators that will eat guppies, but not necessarily be a great fit for a small tank, or do well kept singly. Something like a leaf fish, perhaps, but they really prefer to be in a group and your tank isn't beg enough. Same for many of the catfish that would snack on them.

Doesn't have to be a predator, a rosy barb will do... like most fish over 2" for guppy fry.
