I've never fed frozen mosquito larvae, and I don't know how they are collected, but I'd guess they are probably collected from cleaner water than bloodworms. You don't tend to find mosquito larvae where there are fish present, I assume that this is because they are much more visible at the waters surface, but live ones are a food item that all fish go absolutely wild for.However looking at your statement about commercial collection for bloodworms I’d assume black mosquito larvae would be the same if not worse considering they can survive in almost any body of water even if it is heavily polluted.
I use Grindal worms a lot. They are a lot fattier than Midge / Mosquito larvae, so you need to feed them carefully. I've had bloating with <"Dicrossus maculatus">, and I think the issue was that that I've fed them too many Grindal and Blackworms in the winter.Are white worms not a viable alternative to bloodworms and blackworms?
I try and use live daphnia for this reason alongside the blackworms.think the chitin content in bloodworms etc. is probably an advantage in keeping fish healthy.
Absolutely nothing that I am aware of brings out the "natural" colors of fishes than natural sunlight! ... looks stunning! ... but who know what the fishes themselves are actually seeing(?).
The only time I've seen sparkling gouramis look good in a shop was when their tank had supplemental lighting from the sunWhen I sold fish we had lots of natural light and I would deliberately put the more bland fish in the tanks that got the afternoon sun, where they sold very well.
When I had Black-Neon Tetra (Hyphessobrycon herbertaxelrodi) they always spawned early in the morning when the sun was low and <"obliquely shining on their tank">. If I had a tank that regularly got some sun-light I might go down the "silver" Tetra route, with something like <"Hemigrammus rodwayi">.It definitely helps bring out colouration too, those hemigrammus rubrostriatus in the middle of all the pictures can be quite silver with not much colouration.
They’re hyphessobrycon peugoti. Quite hard to get hold of at the moment but I think they will become more available once people start breeding them. I’m pretty sure these are tank bred due to the price so someone up north is doing it already. I just need to do the same now so they become more prevalent around this way.Beautiful tetra, can I ask what they are?
