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.

    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.

    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.

    Simple the intended breeding pair should be in a tank of their own without fish or other loach. Plenty of plants, hiding area's for adults water temp 21c chunky substrate for eggs rest in until they hatch and to ford protection for fry. Also algea growing on the substrate as this is food for the fry!

I have two loaches. One dojo and one brown. I noticed a couple days ago a slight discoloration in the dojo. The next day it was larger. After 3 days, there appears to be a hole in his face that is just getting bigger. I had the water tested and took pictures to the pet store. They have no idea what it is but suggested anti bacteria to put into the rank. It's not helping. Anyone with any ideas what to do? I've had him hot 2 years and I'm afraid I'm going to lose him

    I've had him almost two years. Sorry about the spelling. Auto correct. Also, I had a brown female and a year ago the same thing seemed to happen. Only with her, her entire upper part of her face seemed to rott away. I did a complete and extensive cleaning to kill any bacteria in that tank. Now a year later, it seems to be happening again. Please help me try to save this one

    It could be pathogenic and so anti bacterial products may not be effective. Instead you can try using a bio-filter safe furan product like Furan-2, along with some epsom salt.

Do I have had a golden dojo loach for about a year,.  He is an awesome fish, very active.  I decided he needed a buddy so I bough anotherone yesterday.  The one I have had for a while has black eyes and the new one has red eyes.  Does that mean he is a true Albino golden dojo loach?  They have LOTs of other loach friends, 3 black kuli loach, 3 clown loaches, multiple guppies, tetras, neons, upside cats and bumble bee cats.  Large Tank

I have a large yellow loach in my tank, among many other types of fish. However, when i cleaned my tank and but him back in it he seems bloated and floats to the top. I feel as if he is tired/annoyed . Iv heard they "fart" air bubbles to rid this, however i havent noticed. Help?

    It sounds like he may be 'gulping' air when he is stressed by the transfer process, which will make them look bloated until the air is dispelled. Perhaps you can leave him in the tank when you are doing maintenance. Do only regular partial a water changes while syphoning the gravel, then you won't have to move him and hopefully you won't have to deal with stress issues.

Hi all, we have two dojos, both which are usually very active. But our bigger one has become sick over the last week. He's very lethargic and his fins dont seem to be moving. He wiggles down to the bottom of the tank and back up again every so often but now spends his time hanging over the filter. Currently doing tank tests. What could this be please help!xxx

    The information you've provided leaves little to go on as to what could be wrong. However, loaches are susceptible to something known as 'skinny disease', which isn't really on disease but rather a name for a condition where the fish get lethargic, stop eating, and basically waste away. If your fish stays lethargic, I would suggest that some type of treatment would be in order.   

    Many fish diseases are Gram negative bacteria. The Mardel brand makes two good products, Maracyn and Maracyn Two, that can be used together for a full spectrum of bacterial infections. Maracyn is erythromycin, and tends to deal with Gram positive bacteria while Maracyn Two is minocycline, and tends to deal with Gram negative bacteria (Gram negative bacteria affects fish when their defenses are low).

    This is a good place to start, but if this treatement doesn't work, then you will need to look at other treatments. Neither of these will affect internal parasites, and neither seems to be active against Mycobacteriosis (Kanamycin can be used for mycobacteria). There are a number of different parasitic medications, but be careful not to use any treatments that are not safe for scaleless fish!

I have had my weather loach for nearly a year. It keeps going upside down and floating to the top of tank, but still alive. I can't figure out what's wrong, can anyone help?

    What he is doing is releasing excess air from his anus. This is normal, as in their normal habitat, they have to survive out of water with their digestive system that extracts oxogyn from the air.

I have 2 Dojo loaches, I love watching them dart around our tank, but one of my little guys/girls is acting rather weird she is looking rather fat around her belly and is staying at the top. She is also farting out air bubbles, can anyone tell me what could be wrong please as I don't want to lose her. She also has a slight reddish color on her tail please please can someone give some advice? Oh I have a 6ft tank with plenty of oxygen. My tank is also going through a cycle at the moment so nitrate, nitrite and ammonia levels are slightly up.

    Red streaks and bloating are signs of a bacterial infection. Treatment with penicillin, amoxicillin or erythromycin should clear it up. Any pet store should carry these treatments. Read more on specific diseases at Fish Disease and Treatment.

i have 2 dojo's they are about 4 years old. They have always been active but the last few days all they do is lie at the top draped over the pump. I have not seen them eat for a couple of days, they do seem to be breathing rather rapidly, every now and then they swim yo the bottom but go straight back to the top. DOES ANY ONE KNOW WHAT MIGHT BE WRONG .

    Check water levels.  How is the water movement?  May want to add some airstones.
Trevor Lingbeck - 2012-12-21
So I'm still kind of new to loaches but I love these fish, they're simply amazing! But this morning as I went to feed them (I have a male and female) I noticed my female has a rather large bump right behind her right pectoral fin. There is no color distortion except for a tiny dark red dot on the bottom of this bump. I'm not sure what it is and it's got me worried. Does anyone have any info or experience on what this could be? :(

    Primafix or mela fix could help.  It could be a bacterial or parasite infection.

    Some driftwood with an attached live plant would make this a happy home for them :)
