Micro gobies?

[Kehy]

Been looking at these guys a bit, going between Trimmas and Evoitas, but I'm not finding a ton on caring for these. What are people's experiences with them?

Mind you, I'm not sure if either of these are going to be an option. After a much (much) needed rescape, I'd still be left with a 2 gallon, 8" cube.

No experience, but Trimmas are known to have very short lifespans (I want to say 2-3 years max?). They're also carnivores, so something like BBS and other small meaty foods would be a good option as well. You can keep them in a colony, but in a 2 gallon, probably 1-2 of them would work. They're not super carnivorous though, I think you can keep them with sexy shrimp.

Got to change years to months to be closer to their actual life span:
Short lifespan and high mortality in the western Pacific coral reef goby Trimma nasa:
"...the estimated maximum age was approximately 87 d, and the
average length of the pelagic larval duration was 33.9 ± 3.7 d (SD), nearly 39% of the maximum lifespan. ..."

They will die of old age by the time they have gone through a proper quarantine...

Eviota can even be shorter lived:
Eviota sigillata - Shortest recorded vertebrate lifespan found in a coral reef fish:
"... A settlement ‘check’ mark in the otolith at 23–27 days marked the transition from open ocean larvae to settlement on the reef. Analyses of the largest individuals showed that E. sigillata has a maximum total lifespan of 59 days, with a maximum postsettlement lifespan on the reef of just 35 days, of which at least 10 are taken to reach sexual maturity (Figure 1B). This provides the species with a remarkable three week window in which to reproduce and contribute to the next generation. ..."

If you want to keep these you better first perfect breeding them...

Hmm, reminds me of killifish and rainbow fish with that lifespan. For those, you can keep them at lower temps to slow their growth and extend their lifespan, but I wouldn't try with frail salt water fish.

Well, uhh, any other ideas? Not really digging the clown goby to be honest

I would think the Eviota and Trimma species you find in the trade live a little longer than the two above mentioned but I wouldn't count on them living much longer than a year, two maybe for the larger species.

A tiny cube like that might be ideal for a few sexy shrimp and some mushrooms...

I purchased a couple of captive-bred Trimma (from Petco, of all places!) a few months ago, and placed them in my 220 gallon tank. As you can imagine, I don't see them every day, but I do know that at least one is alive and well, dodging larger fish and picking up bits of LRS from the current.

Neat little fish!

I used to have a pair of Pellucidas that disappeared as soon as they hit the water (this was in an old 30 gallon). A couple days after I introduced them, I managed to spy them hanging out in one of my Zoa colonies and. darting in and out of a hole in the rock. They never strayed more than a couple inches from their spot.

They're pretty stationary fish, not flamboyant, but not demanding at all. I always assumed they got their share of food during feeding time. By the time I was ready to upgrade to my current tank (maybe a year?), they had disappeared altogether.

I'd definitely get another pair again, but would likely never see them in my 80!

What about a Discordipinna griessingeri. I think they are perfect for a tiny tank. If I ever have a Nano or Pico tank I would get this guy. I think there are a lot of information you can find on successfully keeping these. They need specific are but not hard to replicate these conditions.
Certainly they are beautiful and much longer lifespan.

Here is a thread on this species:

Flaming Prawn Goby ( Discordipinna Griessingeri)

I absolutely love these guys and I want one bad! I'm wondering what opinions are on having one in my 126g? I know these guys are recommended for nano tanks but how would they do in a larger well-established system (loaded with copepods) as part of a community of peaceful but curious wrasses...
