6 months, I’ve had 3 of them and 2 have died, one I see doing just fine, I just love the way they sift through the sand and dive into the sand and stuff, so cuteI love dojo loaches so I know that it must hurt. I have discovered that warmer water shortens their lives and I would be concerned about the red tail shark possibly. How long have you had this particular group together?
Only during feeding, the shark claimed this airstone decoration I have, he just chases them away whenever they got close to him, that’s it though and he does it to all my other fish, my loaches eat repashy super food right off my hand and they tangle themselves into a feeding frenzy when I drop in pellet food, really sucked, the other ones fine thoughGood sized ones too. Really sucks, sorry. Have you noticed the shark harassing them? I had one killed by a black shark grazing on his back, really pissed me off since the dojo would swim into my hand and eat, very friendly and interactive fish. I have also had them breed in a cold water tank
ooooooh...........Idk what to do then, I can't rehome the last one, my tank is unheated though, usually low to mid 70sI agree with Celebrist, dojos are not a tropical species, and to stay healthy need cooler water at times, in the form of a cool down into the 50's or 60sF. in winter They are endemic Asia where snow is common in winter, and water even ices over.
If you want dojos, keep them in an unheated tank with other temperate species like paradise fish, goldfish, or zebra danios, not a tropical constant temp tank.
