Re: Parachromis multifasciatus vs P. loisellei

Thanks Ingo, I remember that many years ago (30, 35 ???) "loiselei" was allready called friedrichsthalii. In that time, P loisellei and P fridrichsthalli were considered the same species. Only in 1989, that is, 29 years ago, the species were recognized as two species. Too bad the wrong group got a ...

Re: Noise and vibration affect Paretroplus parental behavior

Vibrations could also be the key to solving problems with othe Paretroplus species. As fas as I know (not heving experience with any of them) they are all rather hard to breed

Re: Keeping Uaru amphiacanthoides

I would keep them a bit more warmly. For adults the stated temperature is perhaps just acceptable, young fishes generally need it a bit warmer. Better 27 to 28 for adults an 1 degree more for young ones (untill they reach 15 cm). While it is not exactly food, I would suggest adding a few sticks of s...

Re: Crenicichla yjhui, a new species from the Paraná

Cr chelidoculus was, when recentlydescriberd very popular indeed among aquarists. Perhaps it still is,

I wonder what will happen to Cr Yihui, which is most likely easier to keep in winter due to its more northern origen

Re: Honduran Red Point fry

A pair all by themselves is Always a risk. Were there any other fishes in the tank, dithers, other cichlids whatever, the pair would never fight amongst themselves. 56 gallon, US gallon most likely, is some 200 liters of water. That is, your tank will most likely be around a meter length, or 3 feet....

Re: Mayaheros urophthalmus and its subspecies from Yucatan

I wonder, in many cases species are describerd nowadays because they differ more than a certain percentage in their DNA form other speceis. Or, in all honesty, as just a few pieces of DNA are sampled, in case here sufficient difference is found. Apart from the question whehter this results in valid ...

Re: open sores on Geo tapajos, white fuzzin sores

This looks like hole in the head, and is either the result of an infection in the gut, or bad feeding Bad feeding is too much dead animals and too little bveggies. Veggies conain vitamins and minerals, what dead animals contain far less. A gut infection makes it impossible for the gut to get the vit...

Re: Low stress way to remove fry?

a little every day would be the best, and a bottle trap does that.

if the trap is kept too long in the tank, the fry in the trap may die. As you are not going to raise them, this might be not too much of a problem, but you might want to keep seeing this from any young children

Re: Mayaheros zebra

I wonder whether you want opinions. I think splitting up M uropthalmus is nonsense, but that is just what I think.

If the majority of scolars (i'm not one of them) thnks differently, then the splitting up will be accepted. I don't think this majority already has made up their minds

Re: Nomenclature change for cichlasoma

A lot of new names indeed, but fuzzy reading might help. You know "Cichlasoma" salvini? It is now Trichomis salvini. The genus changed, the species name did not. Frankly, it can not change. Still, some species names can change. If the gender of the genus name is different from the old genus, the end...
