Aquatic fLttt 



when completed the female should be 

 removed. 



The nest is carefully tended by the 

 male, falling eggs being replaced and new 

 bubbles added if the structure need 

 strengthening. During extremely warm 

 weather the young appear 36 hours later. 

 Paternal interest continues for perhaps 

 four days longer, during which the young 

 are kept within bounds, which means the 

 nest. Gradually the nest is spread out 

 and new bubbles added, until the fry are 

 able to swim freely. The male should 

 now be removed ; otherwise he will de- 

 vour the young he has so carefully 

 nursed. 



The fry should be provided with Infu- 

 soria in plenty, to be later followed by 

 Daphne. 



How quaint, queer and quizzical are 

 aquarium fishes — and aquarists — to news- 

 paper reporters. In a New York sheet 

 we read of the wonderful "Helleri," 

 which builds a nest of bubbles and then 

 proceeds to bring forth the young alive. 

 Further, Pa Helleri plays hob (we hesi- 

 tate to use a term more in rhyme with 

 the fish's name) with Ma Helleri if she 

 fails to appreciate his attempts at home- 

 building. 



Another paper tells us of a gorgeous 

 red, white and blue goldfish — the "Lib- 

 erty Fish" — originated in northern New 

 Jersey, after years of painstaking effort 

 by the owner. The account assures us 

 that the fish is unique. That the reporter 

 made a careful study of the situation is 

 evident, because he mentions that the Red 

 Drumfish, Bluefish and Whitefish were 

 not called upon to lend their colors to the 

 new animal. Of course, in this new gold- 

 fish, you recognize the popular calico 

 broadtail. Who wants any other kind 

 nowadays? The story reminds us of the 

 romance of Sarjittaria natans, published 



twenty years ago, from the pen of a then 

 well-known goldfish fancier. 



During the famous days of King Ar- 

 thur two brave knights did battle because 

 they could not agree as to the wording 

 on a sign. They were both right and both 

 wrong — the sign had two sides ! 



Since the first stroke of time ignorance 

 has bred strife, and knowledge harmony. 

 Knowledge is the world's greatest asset. 

 Advertising is the power that distributes 

 knowledge. 



Advertising is the point of contact be- 

 tween the producer and the purchaser. 

 Through it public opinion is swayed and 

 action started. The great body of people 

 may only judge a business through its 

 advertising. Judicious advertising, eco- 

 nomical advertising, consists in placing 

 the announcement where it will reach the 

 greatest number of prospective buyers. 

 Aquatic Life is a highly specialized ad- 

 vertising medium for the breeder of aqua- 

 rium fishes, every reader having a direct 

 interest. It follows, therefore, that, re- 

 gardless of the lower or higher cost of 

 space in other mediums, advertisements in 

 Aquatic Life bring the greatest number 

 of orders. 



Krefftius adspersus is certainly a beau- 

 tiful little fish. I have kept specimens for 

 years, feeding mosquito larvae in summer 

 and tiny earthworms in winter. It used 

 to be quite common in our Torrens, and 

 was used by anglers as live bait for perch. 

 Now we must go up the Murray if we 

 want examples for our aquaria. The in- 

 troduction of perch and goldfish in our 

 rivers is without doubt clearing out many 

 of the smaller native fishes. — Herbert 

 M. Hale, South Australia Aquarium So- 

 ciety.
