Chaetodon, but there is no information given 

 in regard to the breeding habits or any method 

 in telling the male from the female. 



Mr. W. P. Seal, Delair, N. J., who no doubt 

 is more familiar with the Mesogonistius 

 Chaetodon than any other fish culturist in this 

 country, informs us that he knows no way of 

 telling the male from the female, and has never 

 been fortunate enough to have them breed in 

 captivity. He further says this is where 

 Aquarium Societies should step in and give 

 to the world, by their experiments, the miss- 

 ing data in regard to this fish. 



We reprint the following letter from our 

 February issue : 

 Mr. Walter Lee Rosenberger, 



Dear Sir: — "Concerning your questions about 

 the Banded Sunfish or 'Chaetodon,' I am 

 sorry not to be able to help you much. As 

 an aquarium fish, it is, as you likely know, 

 among the first of our native fishes. Their 

 breeding habits are unknown to me, though 

 similar in all probability to those of our other 

 Sunfishes. That is to say, they likely make a 

 nest, which is also likely guarded by the male. 



"The fish prefer quiet or still waters, es- 

 pecially where lots of submerged aquatic 

 vegetation occurs in variety. 



"The sexual characters are not often dis- 

 tinct, except when the female is heavy with 

 eggs, when she is more plump in appearance."

The following is an extract from an article 

 written by Mr. F. Schubert, appearing March 

 3, 1914, in the "Blaetter," a magazine issued 

 in Germany : 



"The cultivation of the Chaetodon is very 

 simple. They do not need much heat, ten to 

 fifteen degrees centigrade in winter being quite 

 sufficient. They breed in the spring, and do 

 best in a breeding temperature of eighteen to 

 twenty degrees centigrade. The sexes are dif- 

 ficult to tell, but as breeding time approaches, 

 the male assumes a more yellowish hue and is
