Aquatic liitt 



The coloration varies with age, sex 

 and temperature. Each scale has a 

 golden green spot in the centre, making 

 this the dominant color, contrasting well 

 with the red "trimmings." The female 

 is usually lighter, with the green spots 

 not so pronounced, and further dis- 

 tinguished by a lengthwise black stripe, 

 somewhat broken, and eight to ten verti- 

 cal bands passing down the sides to the 

 abdomen ; these bands are present in 

 the young of both sexes, the males los- 

 ing them with approaching maturity. 



For the propagation of this Haplo- 

 chilus, preference should be given to a 

 broad and shallow, rather than a small, 

 deep aquarium. Rooted vegetation is 

 not a matter of much moment, but plenty 

 of loose Myriophyllum, Anacharis, etc., 

 should be thrown in and allowed to float 

 near the surface. On these plants the 

 eggs will be deposited. At least once 

 every day, and more often if possible, 

 the plants should be examined for eggs 

 If found, either the mass of plants, or 

 the adult fish, should be removed to an- 

 other aquarium. 



The eggs will hatch in about two weeks 

 at ordinary summer temperature, but 

 more quickly if very warm. From this 

 time on, success will depend upon foods 

 and temperature. Keep the babies warm 

 and see that they have plenty of minute 

 forms of life. Eventually they will be 

 large enough to master small Daphne and 

 growth will be quickened. Continue us- 

 ing Daphne as long as it is obtainable, 

 later passing to white worms, and chop- 

 ped earthworms, with prepared foods as 

 an emergency ration. White worms are 

 greatly relished, the fish often leaping 

 from the water to pick them from one's 

 fingers. 



While lineatus will thrive in a compar- 

 V.ively small tank, it should be given as 

 ! .rge a one as possible, especially if it is 



desired to raise fine specimens. In na- 

 ture it reaches a length of four inches, 

 but if aquarium-bred is seldom more 

 than three inches. Heat is a factor in 

 growth, so not less than 70 degrees 

 should be provided during the cold 

 months, while for propagation it should 

 be ten degrees higher. 



The Aquatic Association of Maryland 

 has become affiliated with the Maryland 

 Academy of Sciences, which has been 

 well known in scientific circles for a great 

 many years. While linking its destinies 

 with those of the academy and thus ad- 

 ding an aquatic section to that body, the 

 association preserves its identity and will 

 operate under its own constitution and 

 by-laws. 



At the recent annual meeting the fol- 

 lowing officers were elected for the en- 

 suing year: President, J. Shelton Hill; 

 vice-president, P. C. Chambliss ; secre- 

 tary, William Jay Smith ; treasurer, 

 Louis Hens. 



At the annual meeting of the St. 

 Louis Aquarium Society, held on March 

 3d, officers were elected as follows : 

 President, Paul Hohenstein ; vice-presi- 

 dent, Frank Gutweiler ; treasurer, Frank 

 Moran ; secretary, John Wetzel. 



Carleton E. Davis, Chief of the Bu- 

 reau of Water, of Philadelphia, gave a 

 lecture on "Water Conditions" at a re- 

 cent meeting of the Philadelphia Gold- 

 fish Fanciers' Society. Other societies 

 should find it to their advantage to ar- 

 range for similar talks by local sanitary 

 engineers. 



Crisp lettuce, chopped very fine, has 

 been found to be relished by both gold- 

 fish and wild native and exotic fishes. 

 Even those of decided carnivorous char- 

 acteristics will take it with avidity.
