THE AQUARIUM BULLETIN

young fish are subject to bladder 

 trouble, they should be disposed of, as 

 not a single fish of this particular 

 breeding should be retained — other- 

 wise there will be a strong tendency 

 to create a line of fish subject to this 

 ailment. 



No one should buy a fish simply 

 because it has won some particular 

 prize, because by the introduction of 

 this fish to the tanks, he may introduce 

 a strain which will entirely destroy 

 the previous efforts. 



Nor should one try to procure all 

 results at a single time — one point 

 at a time will give far better satis- 

 faction, and assure success, than 

 otherwise. 



To successfully follow line-breed- 

 ing, the fish must be separated into 

 different tanks — every tank of which 

 should be numbered. Thus your 

 written record will show you that 

 fish in tank No. 1 were crossed with 

 No. 2 — the oft'si)ring being No. 3 and 

 No. -i — etc. 



Invariably the breeder will select 

 strong, hardy stock, as no weaklings 

 are wanted in this im|)ortant proceed- 

 ure — and bear in mind that the buck 

 will produce the coloration required, 

 while the roe will throw the type or 

 shapes required.

THE ANNUAL EXHIBITION 



All preparations are now practically complete 

 for the Brooklyn Aquarium Society's Sixth Annual 

 Exhibition to be held from Thursday to Sunday, 

 September 20th to 23rd inclusive, in the Central 

 Museum of the Brooklyn Institute of Arts and 

 Sciences, Eastern Parkway at Washington Ave., 

 Brooklyn, N. Y. 



This is an event of importance to all fish 

 fanciers and a record breaking attendance is 

 expected. Although goldfish spawn started poor- 

 ly in the Spring, this year turned out to be a 

 banner one for the breeders and many beautiful 

 specimens have been rai.sed and will be exhibited. 

 Many new names will also be noted in the list of 

 exhibitors. Competition will be unusually keen 

 and fanciers in this section will await with 

 interest the decisions of the judges. 



As the tropical fish bi-eeders have been just as 

 successful as their goldfish brothers, visitors will 

 be assured of seeing as complete a collection of 

 those fish as was ever shown. Among them will 

 be the brightly colored rainbow fish, the ruby 

 moon fish and the Mexican sword-tail fish all of 

 which bear their young alive ; the interesting nest 

 builders, the curious mouth breeders, the fighting 

 fish and many other curious, interesting and 

 attractive fishes will vie with each other to attract 

 the visitors' attention. 



This exhibition is an annual event of the 

 Brooklyn Aquarium Society and all fish fanciers, 

 whether members of the Society or not, are 

 invited to exhibit. Owners of well balanced 

 aquaria are especially invited to show them. 



The exhibition will be open to the public from 

 9 A. M. to 6 P. M. on Thursday, Friday and 

 Saturday, from 2 to 6 P. M. on Sunday and from 

 7.30 to 9.4.5 Thursday evening. No admission fee 

 will be charged and the public is cordially invited 

 to attend and become acquainted with the many 

 forms of aquatic life on view. 



Through the kindness of the Department of 

 Parks of Brooklyn, the exhibition room will be 

 l)rofusely decorated with palms, ferns and a 

 variety of other decorative plants for which that 

 Department is noted. In addition to this, a 

 gorgeous display of water lilies of many colors 

 in full bloom will delight the eye of the visitor. 



A special invitation is extended to the members 

 of the Society to attend the exhibition on Thurs- 

 day evening and help celebrate Society Night. 

 A number of our members are unable to attend 

 our meetings regularly, through one cause or 

 another, but all seem to make a special effort 

 to attend Society Night and, if past performances 

 count for anything, a rousing good time may 

 be expected. Attendance on Thursday evening is 

 not. however, limited to members of the Society. 

 Anyone who is interested in aquatic life and who 

 would like to become a member of the Society 

 is advised to make his presence known that 

 evening and become acquainted with the leading 

 fanciers and with the Society. MOTION 

 PICTURES OF AQUATIC LIFE WILL BE 

 SHOWN AT EACH SESSION, EXCEPTING 

 SUNDAY.

 ition may be obtained from 0. H. Chapin, Sec- 

 retary, 479a Quincy Street, Brooklyn, N. Y.
