I really like super vc10 hap. Very pretty fish and a wide range of coloration according to mood and disposition. Hongi is another that I really like the color. I'm guessing after seeing the toadfish it has to be one of the ugliest fish I have seen.
Deepsea anglerfish far outstrip any shallow-water fish in pure ugliness. At least the toadfish mostly looks like something from this planet.
There are a lot of contenders for prettiness, but I'd say either bettas in general or breeding color longear sunfish.
I like oddballs too, but there are some critters that are just undeniably ugly. A lot of them are also venomous or otherwise hazardous to your health, too.
Blobfish look a bit less blobby in their natural habitat, kinda like a toadfish crossed with a tadpole. The poor things just kinda burst outwards when not under immense amounts of pressure.
For me, far, FAR too many fish to possibly call one out as the prettiest.
I could type for pages just on the New World representatives of the family cichlidae alone, then move on to Africa with the same family - that would take pages and pages, and then move on to charcins, the live bearers.
Even making a top 30 list is a fools errand. (for me), if I cared to take the time it would be more like a "pretties 1000"
I mean look at a good red top Afra, or Zebra 'Chilumbae' male in full dress - that's without even thinking about Victorians.
Yeah - fools errand.
Love killifish - don't have any. They give saltwater fish a run for their money. Do have a few Roseline sharks approaching 5 inches. Feeding them blood worms jacks up their red stripe. Females seem to be a bit more muted in colour
I occasionally add live mosquito larvae, then step back to watch them feed, but they're already finished eating. Fast fish - sorta like an aquatic Bugatti. They do better in groups. Sometimes a Siamese algae eater (similar size) will join them in their trips along the tank. They very sociable fish. Ideally they need a long tank, aged water and a fast flow. The latter doesn't seem to be critical as they like messing about low down among the plants and substrate.
I saw about 5 in a petshop in Paarl 2 weeks ago, think they were R70 each, about 7cm long, nice and big but they were very pale. The guy is not the best fish keeper... clean tanks, dirty filters.
He said he can get them quite easily.
