im sure i read a similar thread about this and the answer was the declorinator. What are you using?Jesseschu said:Hi there,
I am new to the cichlid world and new to this site, so thank you in advance for whatever help anyone offers to me.
I have a show tank with all males, including one Calvus Black Congo. I have had the majority of the fish for several months and just picked up the Calvus with a few others.
When I do a water change, he and only he sinks to the bottom of the tank and starts gasping. No other fish are affected this way.
The water I am using is from the tap, but I make sure the temp of it is the same as what is in the tank. I know he likes the water cleanest of all my fish, but I find myself not changing water as often, so as not to have him negatively affected like this.
Please help! Thank you.
Beautiful fish! Not much different than a bcwp? It might be a stretch on my part but,... maybe,... mayne not,... the pearls are a wee bit smaller esp on the dorsal fin. As you said it is a little lighter in your pic than normal.Mr Mbuna said:Here's my male Nsumbu black. Spot the difference between this and a BCWP (if you can). Its a little lighter because of the flash - it normally looks darker than this.
Erm the colour and darkness etc is partly determined by genetics so different calvus variants are not geneticaly the same (though still described as the same species, variants are genetically different from each other)BioG said:The one on top looks a bit like the newer "Livua" variant due to the small spots but without seeing a group with this similarity I would hesitant to say for sure.
The one beneath seems to be more a sub-adult, probably right at 2 yrs. old. They both however, look like southern Congos to me. The blue finnage in the lower
All of this may be mute though because, if you look at some pics of the distribution facilities on the lake shores you will see tons of ponds (I'm guess 2-4 thousand gallons ea?) where they raise "Wild Caught" fish.
I don't really care that they do this but it would, over time, reduce certain traits over generations I should think. Pond raising is a step up from fishroom breeding I think but yet a step down from actual hand caught fish because fish that would be lost to interspecies predation end up surviving with assumed inferior traits in the ponds.
It's important to remember that all "Calvus" are genetically the same just color variants. I've never been patient enough to try it (They grow SLOW) but I would think I could create a white calvus from a congo black strain in 6-8 generations.
You've got nice fish though, imo!
