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.

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.

    I doubt that. Perhaps they got sick on their own. These loaches are very peaceful and will not harm any other fish that I've seen. I've owned Clowns, Dojos, and Golden Dojos and not a single loach has harmed a single scale on any of my other fish. This has got to be the most peaceful fish ever. Very friendly and very non-aggressive.

    I have 4 loaches. They like live food. 2 each gold and japanese in a 30 gal. that completely cleaned my tank of a snail infestation but didn't stop until after eating my gold and black snails I thought were safe. Their tank mates include ghost shrimp for food, 8 cardinal tetra, 2 neon tetra, 2 rasbora, 2 corydora, 2 african dwarf frogs, 2 ea. red, orange, green glow fish, 2 redwag platy to make babies, (Some get eaten, some survive to grow up, watch the inbreeding makes weird fish), 2 otocincleos, high fins, larger snails (Dojos eat gold or black snails if not fed enough-not recommended), 2 guppies that won't leave the platy alone, always trying to eat babies when she's ready to give birth, not recommended with platy, and a couple others I can't recall their names. Everyone gets along great, if you add ghost shrimp or platy add foliage, real or fake for hiding to escape. I don't like to live feed but it is a natural food cycle which I do prefer as an addition to my man made foods. Dojos also like skinned peas. Just pop some cooked peas out of their shell and drop in your tank, pieces of potato, corn, lettuce. All the bottom feeders will love you. Use them to hand feed and train your dojo to eat out of your hand and so you can pick them up and hold them. Be very patient and train em, daily, may take weeks, they are friendly like you but you too would be afraid if you were his size and he your size and he tried to pick you up. Do your weekly water changes and monthly filter changes. Water quality is the most important for a happy pet. It directly affects their entire personality, lifestyle, happiness. You will enjoy them most if they are happy. Water and filter changes go hand in hand and should be done based on how much feeding and excess food is uneaten and rotting. Better to underfeed until you find how much they will eat in about 5 minutes then stick with that amount at least once a day. Do not gauge the dojo eating because they eat when ever so you cannot watch them 24/7. The goal is a pretty clean, not much rotting food environment and you should find success and fun using the fish I've named. When adding fish, consider their full growth size and compatibility before adding. Best wishes.

    Doubtful the fish killed were most likely sick or half dead, if not 1 of those 2 then he was probaly displaying dominance.
