Fantastic Little Fish
I ordered 6 of these guys. All arrived active and healthy. Getting along great with all of my other little fellas in a placid community tank. Absolutely decimating the algae as well. I live in far north Qld. Order was dispatched on a Monday and arrived Tuesday morning. Cant ask for more than that.

Placid workhorse
I was having a hard time with algae for awhile, not anymore! These guys decimated the algae in the tank in no time, and have fattened up and doubled in size. Always active and getting along great with everyone in my placid community tank.

Ordered fro despatch on a Monday which happened late in the day and then the pale and hungry fish arrived at 9:40am next day.

Little shy guys
As soon as I put the bag into the tank the 2 fish knew that it was their new home, they tried to swim down through the bag non stop.
Now they have been into the tank for 3 days they are getting to know the place and the hiding spots in there. Very agile and looking healthy.
Delivery was like 1 day, very fast.
Cheers to Allina that had to put up with all my requests!

Great fish to have in my battle with algae, brought 4, they are going well in the community tank but are still pretty shy. Coming out more frequently now there settled after 10 days.

very small but came out of the bag ready to destroy all algae!
I purchased 2 of these as part of a larger order ... both arrived fit and well. On release they shot straight out of the bags, latched onto the glass and immediately began feeding. I don't think they've stopped since. Excellent little chaps who seem to be growing well.

Lively and useful community fish
I received 10 of these guys about 48 hours ago and they all arrived alive and well. Coloured up almost immediately in their new 1000 litre home and were darting around the plants and driftwood in no time. They were all a lot bigger than 3-4cm, some as big as 6 and maybe even 7cm. Delivery was efficient and the tracking system was very accurate. A highly recommended community fish and I'm already looking at my next order from Live Fish.

All 5 fish safe and happy
Bought 5 of these little fellas. As expected, they arrive scared and had lost their colour. I put them in the tank at 10am and by the time I came home from work that afternoon they had their colour back and were happily swimming around the tank in a school.

No complaints here.

Doing very well
Three weeks after their safe arrival my Siamese Flying Fox fish ar doing very well. They quickly settled into my 3 foot tank with the other fish and are interesting to watch as they go up and down on the glass and weeds, eating the algae. As my tank had black algae and was becoming worse, I had a good clean out of it, replacing weeds etc. and now I hope not to have any more problems.

Learning curve
Ordered 10, 2 were deceased on arrival. Did very much like the strikingly marked little darting fish, and tho I'd supplied plenty of specific hiding places for them, it seems their nbrs have considerably depleted (iv looked n looked over the several weeks iv had them). Chief suspect is my very old, crafty and large ryukin longtail. I intend to order again from Livefish, but def only larger sized species.

Ordered two of these fish - arrived after 3 days, only because I'm in a rural area, so I thought I'd take the chance and order them over the net.....Arrived alive and skittish, but that I was expecting,
I am extremely happy with my purchase and would recommend Livefish to anyone for fish orders and these guys I would not be without again!!!
Really really happy customer, thanks Livefish :))

Excellent fish great for eating hair algae. They were on the smaller side but they grow very fast so nothing to worry about. Going to order more soon.
P.S. make sure you keep the tank covered great jumpers it seems.

Greqat fish
Great fish. they defiantly cleaned my tank of the alge. I had a huge problem so i did my research and bought six of them now my tank is looking alot better..

Not over rated. A very good community fish and can grow as big as 12cm yet at that size still very placid. they like to have a school of about 3 ot 4 but still do okay on there own. i find it very hard to breed them and rarely breed in captivity

good addition
Lively fish that squabbles with his own kind. In my opinion overrated as algae eaters unless minimal food is added to tank. This fish will greedily eat anything and neglect the algae. Bristlenoses in my opinion are more effective for algae control.
Excellent quality fish from live fish though.

2 eaten 1 survived
An update.

The two that were eaten... well that's just tough luck.

One has managed to survive and is quite large now.

If they were sold larger they would survive better in my tank.

Great fish
They were tiny when I got them, was worried another fish would eat them by accident. But they grew fast and turn into attractive and very efficient algae eaters. Two of them keep my 200L tank spotless and if I drop in some plants that do have algae on them from my other tank, they're onto it straight away and clean it up ridiculously fast without damaging leaves. Make sure you give them some zucchini to munch on :)

They get along with all the fish in my tank and like to be in a group. Nice hardy fish and good "housekeepers"
