Hello there I am trying to breed the dojo weather loach for the past 2 years, I study fish husbandry and fish biology and am a lover for fish through and through! I have six loaches in a 4ft tank with a ehiem external filter the tank consists of a large mix of fish naming a few, carp, tench, red tailed shark, one large coldwater plec, one medium tropical orange spotted plec, large fresh water mussels,
one of the loaches is now around 7 inches and has a large belly (egg sack looking). I have the temp quite high and have been increasing it over the last 2 years now it looks as she might lay eggs. My question is what do I do leave her and reduce the other fish stock or try and catch the loaches and move them into a smaller hatchery tank? Please get back many thanks neil xx

    Do you have warm enough water?
  • chris - 2011-04-05
    All of your fish may be bothering the loaches, so it will be harder for them to breed, and you may have to have warmer water.
  • chris - 2011-04-11
    It might be a disease called ick.

    Uum even if you do get breeding fish with other fish like that in the tank they will eat the eggs, plecos and carp and the sharks will make quick work of any fry too. Highly recommend moving them to their own, shallow ish but big tank (much like a ray or skate tank) with a area of lots of water movement (as dojo loaches will often lay eggs in direct current to keep them oxygenated) and an area with a lot of live plant and little current for hiding as a breeding pair may be shy and these are smart fish and will see you around if you come into the room.

    They need cooler temperature to breed... Like 20 or lower... And apparently they don't breed in captivity :/

    I have 2 loaches 1 of them is a weather loach. One of them jumped out of the tank and stayed on the floor all night. Next morning I found him on the floor. He always dug in the gravel. I think loaches are the best pet ever!

    Weather loaches are a cold water fish, breeding is triggered in coldwater tempetures ,around 64 farineheight. I would do breeding in long tank. They like to chase.
  • Jeremy Roche - 2012-04-14
    I would move the fry so you don't end up stressing your community out too much. If a small community tank and you have another established tank you can move them.
  • Renz - 2012-04-26
    Separate carefully the other fish from loach, for them to breed and to release eggs. Put also any aquatic plants inside the tank for the eggs to attached and hatch. Supply them with continues water flow inside the tank.

I have 2 loaches (Ken, and Sven), Sven likes to drape himself over the stuff in the tank and he looks like he's posing, and Ken, the larger of the 2 likes standing upright which, I think is a bit strange, but he seems alright!

    You can try flakes and pellets at the same time. I have the same scenario but I try to aim the pellets where my pearlscales wouldn't see them or couldn't reach them. There's a lot of microscopic food that WE don't see but our loaches find it on the bottom... So I wouldn't worry too much

    They just don't 'jump out of the tank' they just jump and it happens to land them out of the tank. Tank covers.....

Well, I got a dojo loach with discus in 27.3 degrees celsius. It's fine :) Scooting around the tank and swimming together with my cory cats. It's such a nice fish! :) So I think that 27 degrees is fine for them, at least if you do a weekly water change where you pour water in that's about 2 or 3 degrees colder, to make it seem like fresh rainwater :)

PLEASE HELP! I have a more pink colored Dojo and have had him for about 6 months and he has been sick for over 2 weeks. He has bubble looking masses by his tail and hemorragic striping down his back fin. Now his gills are starting to swell I have done different meds, had the water tested and I'm at a loss of what to do now.

    have you tried salt and adjusting temp up a bit? Ammonia levels good?

Hi my dojo is one of my favorite fish :) but just today its been extremely laid back-clam, and staying to its own. and lighter in color, or I could just be freaking out. Tomorrow I am checking my tank and everything like that. Is there any suggestions. Like I said it's one of my favorite fish so I'm really worried! thanks

    Sorry:
    also, none of my other fish bother it. I have a very peaceful tank. and I've had it for about 3 months and this is the only time its acted strange.
  • anna phillips - 2012-02-27
    Check your water conditions, loaches are very sensitive. He might also be resting, my loach does this and sometimes loses coloring.
  • Jeremy Roche - 2012-02-28
    Have you done a water change recently? Any water temp changes? If not check your ammonia. Have you added any other fish to the tank that may be harrassing it? I would start with an amonia test right away.

    Try looking at the article Fish Diseases and look under constipation, parasites and fungal diseases. See if the symptoms apply and if so the corresponding medication is listed. Good luck.

I would like to know what fish go with loaches...I have two loaches and some guppies in my tank. However my loach is being eaten, so it appears to have a lot of flesh missing on the back quarter. Can anyone help me with this, I do not want to lose the loaches, I find them so beautiful. Thanks.

    The Dojo is normally a good community fish and gets along with most. Are you sure the loach is being eaten by the guppies. Could it have gotten stuck under a filter or cok or bruised somehow. Can you move it to a smaller tank, check on it and treat it if necessary?
  • pat - 2011-08-03
    I thank you for your response but my dojo passed away sometime during last night. It was eaten by something but I am not sure what. It had part of the spine exposed and you could actually see bite marks in it. We took it out to investigate and we found marks all over its body. I will miss it for sure because it gave my grandkids lots to watch when it performed.
  • fishyhelper - 2011-09-10
    Sounds like a bacterial thing or a wound thing. They are scaleless so if there are any sharp rocks that they are trying to burrow under that could cause it. The other possibility is a parasite. Go see a good fishy doc. It's rare they get ich but it could happen if it starts with a wound.

    what does the dojo poop look like

Gail - 2011-07-17
My Dojo is a real hoot. It's active and no one bothers it. I have mostly tetras (small and large) and few unusually unaggressive barbs. I have a Pleco, tire track eel, gouramis and even a blue lobster. I'd transfer your Dojo to an isolation tank and bring it in to a really good fish doctor. It sounds like either a bacterial problem or it got wedged under something and got wounded trying to get out. Either way I'd treat for possible infection in its own hospital bowl or tank.

    You're right and I can't find the person you responded to. If you can go back - please. Good answer and thank you. Glad you enjoy your Dojo.

Does anyone know how to breed them?

    It has been said they have been spawned accidentally, scattering tiny red adhesive eggs, but not much more is known about the breeding habits of the Dojo Loach or Weather Loach and they are not yet bred commercially.

  • chris olson - 2011-06-01
    YOU HAVE TO HAVE AT LEAST 75 DEGREES TO 80 DEGREES AND TO KNOW IF YOUR LOACH IS A MALE OR FEMALE, MALES HAVE LONGER FINS THAN A FEMALE. :)
  • Jori - 2011-06-24
    These are pond and stream type fish. Often times keeping them in a shallow but large tank (like a skate or ray tank) with a high current area will do the trick. A breeding pair may use the current to oxygenate the eggs. There should also be a low current area with lots of live plants to give the potentialy shy fish a hiding place. Dojo loaches are smart fish and will know if your in the room and no animal of any level of smarts is going to like a peeping tom.
