Who Gives A Fish Forums

See my previous post from 2021 below for some background. I recently lost my oldest loach, who was 17 years old, and I'm really concerned about the remaining loach. He's about 16 years old and was always the bigger, healthier one, but now he seems less active, spending more time at the bottom of the tank. I've noticed he appears sad and lonely, which is understandable given their long history together. I'm hesitant to introduce new fish, but I think he needs a companion - possibly a new loach friend. Should I add one or more? Before his tankmate passed, he was still very active and protective of his friend. I do have a quarantine tank ready for any new additions. Given the tank size (30 gallons) is limited by room constraints, I'd appreciate any advice on how to proceed.

I'd definitely recommend getting another clown loach, or even two. They seem to thrive when they have some buddies to hang out with, and since your remaining loach is already showing signs of loneliness, I think it would really help to have some new friends for him.

Sorry to hear about the loss of your loach. 17 years is quite an achievement, especially considering the tank size - it's clear you've put in the effort to care for them.

First things first, keep a close eye on the survivor for now. If the other loach died from an infection or something contagious, the lethargy could be a sign of something more serious. I wouldn't want you to stress the survivor or a new fish by introducing them too soon. I'd recommend waiting at least three weeks to observe any changes.

You've done a great job with these fish, and it's evident in their lifespan. However, I have to say, the tank is on the smaller side. Are your loaches actually tiger botias or clown loaches? There's a difference, as tiger botias are often referred to by the trade name and are actually part of the Syncrossus species, whereas clown loaches are Chromobotia macracanthus.

Once you've cleared up any potential health issues, you can start thinking about introducing a new loach or two, as FunFish suggested. Just make sure you're prepared to provide the best environment for them.
