How long could a tomini tang thrive in a 45g aquarium? I'm not talking about how long could they live, I'm talking about happily living in a tank that size. I'm always wanted one, but I have a 45g aquarium and I've heard they can be fine for a few years and then I'd have to trade him in. I know I get attached to my fishy friends and it would be a sad day when the time came to say so long friend. In hindsight I should have bought the 65g aquarium because I fear that I have an uphill battle with my wife coming should I decide to ask her about getting a bigger aquarium when the time comes.

I am not looking to add an animal that won't be happy in my tank. If a tomini tang won't be happy, I won't pursue the idea.

Same here. Been in there 2 years, Waterbox 50.3. I think this is a good candidate for this tank.
 
I know your not asking me, but it is a light load. 3 green chromis, a storm clown, and a gramma. He is the largest of the 6, but still small overall with good coloration.
 
WOW! what other fish do you have in there? I don't want you in trouble with the tang police, their under cover agents are everywhere.
Yes they get intense…I have 3 fish: tang, 6 line, Royal Grammy.

I have kept dozens of tangs, some are only suited for large tanks. Tomini Tangs seem the exception. I have not noticed any behavior issues. He acts similar to tangs I have had in large tanks. Here is my 300+ gallon…

I've always wanted one but I've been nervous about how it'd work out in my tank. I have a midas blenny, watchman goby, a yellow coris wrasse, mandarin, and a springer damsel. THe watchman goby and the six line wrasse are the jerks of the neighborhood The watchman goby doesn't even like snails in his den. I also have a lot of LPS coral, hammers, torches, frogspawn, blastos, and sps
 
I’ve kept plenty of tangs and they are very messy fish. They poop ALOT. That alone would keep me from putting them into anything under 80 long term. The water quality and nitrates in a small tank will be a problem eventually.Thats just me though. It’s your tank so do what makes you happy.

So many factors there. I still wouldn’t do it. I’m sure you’re dosing for nitrates and doing weekly water changes to keep a uln system. That’s what I do along with everyone else keeping nitrates that low. Not everyone is gonna do that. I’m by no means tang police. If you’re not willing to do the work it’s not gonna end well for anyone.

I do weekly wc but for coral growth and tank health. Only use a protein skimmer, no carbon dosing or supercharging bacteria. I wouldn’t describe my system as ULNS. I wouldn’t recommend a tang in a tank as small as mine but it is doable for an experienced hobbyist imo.
Just now and he seems very happy….imo!

I can't recommend it.
It's one of those ideas that passes through my head and then fades away. I doubt I'll do it for a lot of reasons. The biggest is it's a $120-150 gamble of will it thrive in my aquarium. The other reason is will the fish be happy. Tang love to swim and my aquarium isn't big enough for what they want.

I've got a Tomini in a small tank, about 75 actual gallons, but it's a custom 72x24 inch lowboy tank.....lots of area. That's the only way to an exception, and isn't really much of an exception.
 
Meh, I think it's too small even for Tomini. I personally don't find the smaller tangs that interesting personality wise. Something like a Midas blenny would be a much better fit.

I have one of those. He's one of my favorite to watch. He's best friends with my yellow coris wrasse and after she goes to bed he spends his days grabbing sand and spitting it. He's the peacemaker of the tank, if my six line wrasse gets to feisty he steps in and says back off. He even stares at the lid when I put the jar of food on the top. My CUC is keeping the algae at bay for now so I'm not getting a tomini tang. I'd love a tang some day.
 
Another question I have is IF I were to get a tomini tang and let him live in my 45g, how susceptible would he be to ich? I have a UV sterilizer.
 
Seems that the suggested minimum tank size for a tomini tang is 70-75 gallons.

While I've read (even in this thread) that people have housed other tangs and they simply only grow to their environment, I tend not to believe that, and I would not get a tomini for your tank.

I've only had my tomini for a year or so, and he's probably 4 inches long.
