Conaquavict Posted January 16, 2006 Author Report Share Posted January 16, 2006 Here you go Mystic, i will get you a full tank shot in a few days time when i'm not so busy, lol, this shot is a few months old and the fish are bigger now there are also 4 hiding, Quote Link to comment Share on other sites More sharing options...
Tanksman Posted January 16, 2006 Report Share Posted January 16, 2006 Thats cool mystic - I'd love some frons but I need a bigger tank - They need 500 litres don't they? Quote Link to comment Share on other sites More sharing options...
Tanksman Posted January 16, 2006 Report Share Posted January 16, 2006 Do you have them in your 600 litre tank - What else is with them - I'm nosy as I'm just setting up an african tank. Quote Link to comment Share on other sites More sharing options...
malawi_man Posted January 16, 2006 Report Share Posted January 16, 2006 man i love those fish, shame i dont have a spare 6-7footer. They can go with malawis but the malawis will probabll pick on them. The require similar conditions for water quality with the frontosas pH being anywhere from 8-9??

malawi_man Posted January 16, 2006 Report Share Posted January 16, 2006 what is calcite?? i use aragonite in some of my tanks, keeps the pH and kH high. Sea shells and limestone i think are both good for this as well. there is lots of limestone near here, a bit like oamaru stone. Quote Link to comment Share on other sites More sharing options...
Tanksman Posted January 16, 2006 Report Share Posted January 16, 2006 Calcite must be a brand name as it is lime stone is it not? What Ph does calcite hold and where do you get it mystic? Quote Link to comment Share on other sites More sharing options...
Tanksman Posted January 16, 2006 Report Share Posted January 16, 2006 and because of the weight also, shipping is expensive! I'd say Aragonite is technically unstable at normal surface temperatures and pressures. It is stable at higher pressures, but not at higher temperatures such that in order to keep aragonite stable with increasing temperature, the pressure must also increase. If aragonite is heated to 400 degrees C, it will spontaneously convert to calcite if the pressure is not also increased. Since calcite is the more stable mineral, why does aragonite even form? Well under certain conditions of formation, the crystallization of calcite is somehow discouraged and aragonite will form instead. The magnesium and salt content of the crystallizing fluid, the turbidity of the fluid and the time of crystallization are decidedly important factors, but there are perhaps others. Such areas as sabkhas and oolitic shoals tend to allow significant amounts of aragonite to form. Also metamorphism that includes high pressures and low temperatures (relatively) can form aragonite. After burial, given enough time, the aragonite will almost certainly alter to calcite. Sedimentologists are very interested in aragonite and calcite stability fields because the conversion of aragonite to calcite after deposition has a distinct effect on the character of the sedimentary rocks.

Tanksman Posted January 16, 2006 Report Share Posted January 16, 2006 All I really want to know is what is the best thing too put in my tanganyikan tank (which will be using Hamilton water - yes the nice browny green stuff that we pollute before it arrives in Auckland. ) and where is the best place to get it.

Caryl Posted January 16, 2006 Report Share Posted January 16, 2006 I am probably heading thru ChCh next month then will be in Auckland Easter weekend. If someone is wanting this calcite stuff, I am happy to get it and bring it up with me if you're willing to wait. Save freight. I have a Honda Odyssey and will have 5 adults in it (3 of them not lightweights - but don't tell them I said that) so don't ask me to bring too much! Not sure how much of a load I can put on the axles :lol: Quote Link to comment Share on other sites More sharing options...
malawi_man Posted January 16, 2006 Report Share Posted January 16, 2006 your calcite look pretty similar to arangonite to me. aragonite keeps pH at around 8.2 and kH anywhere over 10 which is good because africans like hard water. mystic, do you have an 8 foot tank?? i have aragonite in most of my filters, the water goes through it after the carbon and that helps the pH stay high. i have nothing apart form that in my filters for my 800litre tank and it seems to stay about right so i'm happy. i might have to put some in the new sump i am making.

Conaquavict Posted January 17, 2006 Author Report Share Posted January 17, 2006 Hi guys i have the fronts in a 75g at the moment, they will be moving to a bigger tank of course when they get bigger, The subtrrate is a mixture of coral sand and coral gravel and the ph stays at 7.9-8.0, they seem to be thriving at this. Does anyone know why fronts are so slow growing cmpared to other cichlids and why one fishs usually a dominant male will grow 3 times faster than all the other fish? Btw.. Out of curiousity how muh do fronts retail at in NZ? You an pay £10-£15 for them here in Ireland. sorry for all the questions, Quote Link to comment Share on other sites More sharing options...
malawi_man Posted January 17, 2006 Report Share Posted January 17, 2006 anywhere from $50 up. the dominant male will let out hormones which will stunt other fishes growth otherwise the biggest fish is normally the male anywhay Quote Link to comment Share on other sites More sharing options...
Conaquavict Posted January 17, 2006 Author Report Share Posted January 17, 2006 $50 sounds a lot, How much is that in sterling? (British pounds) Quote Link to comment Share on other sites More sharing options...
Conaquavict Posted January 17, 2006 Author Report Share Posted January 17, 2006 50 New Zealand dollars = 19.684282 British pounds. So fronts are not a cheap commodity in NZ then, $250 - $300 is crazy money, Quote Link to comment Share on other sites More sharing options...
craig Posted January 21, 2006 Report Share Posted January 21, 2006 hi, frontosa don't reach breeding maturaty till 4-5yrs so i guess that has something to do with why they grow so slow. very much worth the wait. in my tank i have never noticed that male hormone thingie. the two colony's are all the same size,both males are alot bigger than the girls and the girl's are of equal size (7yrs) as with the males,they are still growing. they are in a 6-2-2, 9 adults. calcite substrate and dolimite rock, ph 8.4 hardness 20. when i work in the tank for any length of time my hand's come out quite white and rough. front's don't like the temp to hot 24-26max and hate fine air-bubbles eg. spray-bar running on surface of waterline.these are just some handy hints i've noticed over the years with these fish. i not long sent some up north, they were 2 day's in bag's(due to courier foul-up)should have been overnight delivery,thank's to fantastic packing and fine weather all 6 fronts were fine and are swimming around happily in their new home. 41hrs all-up, so definitely proves my theory on temp. you guy's are going to have alot of fun watching your front's grow, mystic your bubba's are growing well. :lol: shell Quote Link to comment Share on other sites More sharing options...
