Probably a school of 5, and that would be pushing it. Not because of the bioload, but the swimming space. These fishes have a 2 inch fish bioload, but can grow about 3 inches big,

Blub,
Any suggestion on what to put on the intake part of the filter? hatchet fish are on my stocking list for my new tank and I am glad that you made me aware of it.

i thought they got to 2 inches and about 1 inch or 1.5 inch bioload but i could be mistaking.

sorry no trying to hijack the thread

I have 4 marble hatchets in a 20 along with some other fish. They are about 1 inch long, I assume they are not fully grown. They seam to be pretty happy. I would go with a school of at least 5, i plan on getting more for my current 4. A 10 gallon aquarium for a whole school of hatchets is pushing it pretty far. I think it was a good idea to wait for another tank. Good luck!

Watch the betta and hatchets - I've never tried to combine them out of fear for the hatchets. It may work though, but I guess it depends on your Bettas personality. Hatchets are peaceful fish that confine themselves to the top I suppose - which is like corys (except they stay at the bottom) so the combo may work.

David - sorry for the late reply! I'd put any kind of aquarium safe meshing stuff on the filter; you may of course not have that problem, as many people don't but I seemed to have it a lot.

Mjordan - that would be overstocking as hatchets ideally need at least 20gals of space, as they only use the top space and a in 10gals they wouldn't get much swimming space. They do have a vey low bio-load though ,due to their slim body shape.

i just cut a whisper biobag (lots of extras from my whisper filters that came with kits) in half and use fishing line or cotton thread to attach it

I think the reason the Betta doesn't attack the hatchets is because their fins are so short. Long fins attract Bettas because they look more like their own.

Blub

Yeh I once knew someone with a female betta with fancy guppies... And I tell you those gup's tails looked like stubs!

mrfish

That happened to a long finned danio that i had. I didn't think about the long fins. It was pretty stupid of me. A couple of days later, those fins were shreds.

I had to move the Betta to a different container for a while.

mrfish

Wasn't fun for it i bet.

mjordan

so blub do u think i could get away with 4 hatchets in the 10g or do i need to increase that school. only prob. is that i not realy able to put them in my 30g unless i switched the hatchets for my neon tetras which im not really looking forward to if i were to have to....


thatnks and im hopin 4 a reply

Blub

Hatchets need a 20gal at least... As I stated before.

mjordan

ok so i guess i will rework my stocking plans.
