Rainbowfish lecture at Kirkaldy Aquarist Society

Last Monday, C.E. Fish Essentials Ambassador & well known rainbowfish conservationist (and enthusiast) Alex Carslaw was once again invited to hold a C.E. sponsored seminar on ‘Breeding Rainbowfish & Blue Eyes’. This time it was at the Kirkaldy Aquarist Society, Scotland. Here is Alex’s account..

I always look forward to my visits to Kingdom of Fife, whether it be for an open show, an auction or to speak at one of the club meetings. Kirkcaldy AS is a popular and long established club, formed in 1927 and is part of the Union of Scottish Aquarists. The club has its own premises at 21 junction road, Kirkcaldy and the first thing you see after you have climbed the old stairs is the certificate covered walls and trophy laden shelves of the meeting room. This visit was to present a lecture on the breeding of Rainbowfish and Blue-eyes. Breeding these particular fish is pretty straight forward however raising them can sometimes prove tricky, particularly the smaller larvae such as Iriatherina werneri.

The lecture covered my 5 key steps to success.

1 Fish Selection

This section features some highly important issues such as inbreeding depression and maximising the diversity of your genetic pool amongst other topics.
2 Preparation
Recreating environments which the target species view as desirable for breeding can be difficult. Covered here are my set ups for successful breeding and the conditioning of selected fish for maximum fecundity.
3 Methods
Different species tend to adopt varying methods for breeding and here I speak of the different spawning methods used by various species
4 Hatching Eggs
In this section I highlight the topic of hatching eggs and the associated difficulties one can encounter at this stage, as well as how best to tackle these problems.
5 Raising Fry
Arguably the most difficult aspect of this process is the successful rearing of high quality fry. In this section I explain in detail the methods I adopt for correct feeding of fry with varying sizes through their growth stages as well as how to provide the optimal environment for best development.

As always, a warm welcome was given and appreciated from this fantastic club and I look forward to returning after the summer where I will be talking on the subject of Rainbowfish Identification.
If you live nearby why not join up as I’m sure you will be made most welcome. The club meets every Monday evening at 7.30pm. Details for the clubs annual open show and auction can be found below.

Alex Carslaw is without doubt the U.K’s most dedicated Rainbowfish enthusiast – award-winning in fact and he has made it his passion to become a significant contributor to the field in hope of preserving both their keeping in the aquarium hobby and in many cases stabilizing a future for several species of these graceful, diverse and unbelievably underappreciated fish. Alex has been keeping and breeding fish for just over 30 years and his passion for Rainbowfish began with a consigment of the stunning Melanotaenia boesemani which he encountered when working for a Glasgow importer of tropical fish. Alex is a great believer in the power of social media and has used this platform to create a worldwide network of Rainbowfish enthusiasts through his Facebook group and personal website. Alex’s work, whether his hours upon hours investing time & money into his fish, or researching, learning and teaching others about the wonderful Rainbowfish of the world, helps to keep raising awareness for many Rainbowfish which are in urgent need of protection. Some of these species originate from single lakes in what are now ‘developing areas’ and hence being destroyed, polluted or filled with invasive species which are outcompeting or even predating upon these pressurized populations. For some of these fish, their propagation within the aquarium hobby is their only chance to remain on earth.
