How do I get rid of hydra in my fry tank, my current batch of peacock gudgeon seem to be too big for the hydra to catch but I have eggs that should be hatching out today or tomorrow and they will be munched, what do I do

I have a 5,10,20 gallon tank and I want to know what fish could be bred using them that would bring back the most amount of money.

I have a 20 gallon that I would like to house with rams. I'm trying to decide between the 2 types. Im wonder which would be better depending on how hardy they are, and which are bred easier. I have a 10 that can be used as a fry tank if needed.

Hey all, this is my first time posting, and admittedly a relative beginner. I'm just beginning to stock a new planted 110, and moved over two black phantom tetras from an old 29g. I noticed that they're courting a lot in the new tank, which they never really did in the smaller... then...

I finally got my GBRs from oddballfish.com:) They arrived quite shaken up because the bag leaked slightly and there was about 1/4 of a cup. The gels that the bags come with to absorb any leaking of the water was soaked. They arrived around 3:00 today and both already have some nice color though...

So I have this little "for fun" experiment in mind where I want to make some Guppy/Endler hybrids and see what I come up with, mostly I want to see if I can get a clutch of fry that have endler looking males with less dull looking females. But I'm intrigued to see what all I come up with, and...

the title might sound stupid, but I'm just wondering because my guppies is fully bloated with eggs [i think] for 1 week now, maybe more, and I still havent seen any fries anywhere. is it that i put them in a 25cm cube [4gallons] tank so they dont wanna breed or they're just slow 'gestating' or...
