Smallest Fish for the Aquarium?

Hello,

I was under the impression that tetras are the smallest aquarium fish (in terms of length). Would anyone care to differ?

Thanks!

I agree with Yoink. You aren't going to find much smaller fish than micro rasboras. Check out Franksaquarium. Most stay 3/4" to 1" fully grown. My boraras species came in today, in fact, and they aren't much bigger than 1/2" and won't get much bigger than that.

The smallest fish in the world lives in Sumatra acid pools. It is a type of carp and doesn't grow any bigger than 6.5 millimeters! But you can't buy them.

I've got 20 of these fishes called Danionella spp. They are transparent and about less than 1cm long. These guys makes my micro rasboras look like giants because of their slim profile. In fact they look like the fry of some other fish. The other fish I have is an Indostomus paradoxus, about 1cm long but they are thin and are much nicer looking than the pic. I have 4 of em.
The last I don't have a pic but they are gobies and are colored like bumblebee gobies but way smaller. I have 4 of the smaller ones about 5mm long and 2 more not as well colored and slightly larger (might be a different species as well). Their build is not as bulky as bumblebees; their bodies taper off towards the tail end like those mini puffers. I keep them in a 1ft tank with various shrimp and shrimplet as well who are unharmed by them.

Sorry for the late reply. I live in Singapore and from what I heard from the shops here, many species are re-exported to other countries from here. The local shops sometimes get a hold of some of them if it tickles their fancy. Only two shops in Singapore had them. I managed to get most of em. Hee hee. There's been a new batch just in a few days ago.

Mine are doing great...all accounted for. My first batch of 10 from about 3 weeks ago are all fine. The second batch of 10 are much smaller in size and are about a week old. For the live food, I feed them daphnias, baby brine shrimp and also fry food like Sera micropan (I mix it around in the tank so it looks alive). All the tiny fish I have are in my 1ft shrimp tank. Fortunetly I have 2 shops that I regularly buy live food that stock adult Brine shrimp and worms as well. All my fish in my 6ft tank are fed with live food as much as possible as well. I find the fish more lively and healthy because of the huting they get to do more than nutrition value I think.

These are crap pics of the smaller goby and the pipefish. I used a Nikon D70 but unfortunetly no macro lens so it's near impossible to get good pics of them. My next try is with a compact camera with a macro mode. I tried it and it can do the job so stay tuned...I'm adding a horrid pic of a 1ft tank with a wide shot of the glass fish, micros etc and the (gasp) purple shrimp.

Sithspawn, don't hit yourself over your head for your photos. You have great fish. I wish they had that variety here in Canada (sigh). As for macros, if you're steady with your hands and have a removable lens, use your 50mm and reverse it. You won't have clear control of the lens, but you will have a massive macro. Those gobies are cute!:eek:
