Dear readers
I'm Sophie my first contact with les the author, was when I sent him an e-mail regarding bringing on my first batch of Dwarf Gourami fry. Below is a series of exchanges giving advice on both sides of the wire. Through mutual agreement we decided that perhaps the first time breeder can learn something from these exchanges below, the text has been edited to remove irrelevant chit chat. Date: 26 June 2007 Sophie I was wondering if you could help me? I am currently the proud carer of approximately 200 dwarf gourami fry (five weeks old). They're growing well with both tank, and water parameters good, they are feeding well on newly hatched brine shrimps. The question is at what age should I start to give them other foods? I am concerned they will not get everything they need apart from newly hatched brine shrimps, any advice would be most appreciated. Reply Let me congratulate you; firstly it depends much on the size of the fry. See the fry on my website photo, well believe it or not I have a good few that are ¾" long and others that are not even ½" long, they were all hatched on the same day, nonetheless these young Gouramis are well passed the brine shrimp stage and should be eating adult food stuffs exclusively. Ideally you should grade them by size then seperate the larger ones by putting them into another suitable tank. There's a case also to be said about harrassment, and bullying by the larger fish. Separate them by sizes even if you use a tank divider, which I do. This will help the smaller fish reach more food and gives them more confidence in becoming less stressful. |

Sophie I happened to notice today that the largest fry are starting to go red on their fins (its funny the kick you get when you notice changes like that). You mentioned the high mortality rate with the fry of the dwarf gourami, they're so tiny at birth, I suppose it's as much a reflection on their breeding habits, loads of young equals a higher death rate! I'll be happy with any I rear onto adulthood, as this is my first time at breeding them. Date: 20 July 2007 Sophie I'm now passed the eight week mark but I've had a large number of casualties (50-70) at the six week stage. I'm doing 50% water changes utilising treated tap water on a daily basis, also they're fed exclusively on high quality dry flakes (unpowdered). Many are developing their adult colours, and there appears to be more females than males with about 40:60 ratio males to females. The tiny runts (funny they don't seem to get any bigger) all hang about in the planted area. I mix small crumbled flake with tank water and then use a syringe to feed them directly into the plant area, that way they don't have to run the gauntlet with the big boys it works well. In this hobby I've came to accept the good and bad without being indifferent! Finally I realise that I've a long way to go yet, but getting 150 odd Gourami fry passed the 8½ week mark can't be bad for a first timer? Reply You sure have excelled in the numbers department, but you must be concerned about the high death-rate amongst the rapidly growing gouramis! I think we should stop calling them fry as they're half way to becoming adults. You're correct on the runts I always noted that a very small number just never seemed to get any bigger, they eat but the don't develop into adults (strange but true). I also use a plastic syringe for feeding my tiny fry brine shrimps as you have more contol, directing the shrimps to where the fry are gathered, that way most of them get eaten and not wasted when sinking to the bottom of the tank. Thanks for sending photographs of your breeding tank, they will perhaps illustrate the dangers of overstocking to the beginner. |
