Lemonpeel Angelfish (Centropyge flavissima)

(Centropyge flavissima)

This weeks fish of the week is a striking member of the dwarf angelfish family - the Lemonpeel Angelfish. Their electric yellow body with blue highlights around the eyes and gills make it one of the most popular dwarf angelfish in the hobby. Not to be confused with the similar looking Heralds Angelfish (Centropyge heraldi). This mimic is distinguishable by the lack of blue highlights. It is also sometimes called the False Lemonpeel Angel. Having been discovered 122 years later, one has to wonder if it had been found first, whether our fish of the week would be the one labelled false!?

 

Whilst only attaining the modest size of 10-12cm, the Lemonpeel Angelfish needs a large aquarium of at least 250 litres for long term care. They are a very active fish that can be territorial with other dwarf angelfish, or fish of a similar colour.

 

Like many dwarf angelfish species, it is not considered reef safe. They are prone to nipping on LPS corals and especially the mantle of clams (the fleshy part). They consume a lot of algae in their diet, so should be offered a good quality spirulina-based algae flake. Also look out for specialist frozen pygmy angelfish food in stores - it includes clam meat and marine sponge to recreate their natural diet.

Some species of dwarf angelfish are now available captive bred. During these captive breeding efforts, an interesting behaviour was discovered. It is now well known many fish species have the ability to change sex. Most of these fish do so unidirectionally (clownfish, for example can only transform from male to female).

 

Research over the last 20 years has shown some Centropyge angelfish have the ability to transform bi-directionally. Scientific experiments by Sakie et. al. 2003, observed both males and female Rusty Angelfish (Centropyge ferrugata) changing sex. The biological transformation was observed to occur within 50 days, with mating ritual behaviour starting after approximately 30 days.

Koi Water Barn and NT Labs have a long history of working together, we feel that the products in the Koi Care range offer our customers a quality product at a realistic price. This is backed up by extensive research and development that is carried out at the NT Labs HQ located in Kent. They are not far away from our shop at Coolings (Knockholt, near Sevenoaks), this is an added bonus for our customers as they are buying from a local UK based company.

We have been working closely with NT labs for many years now. We stock their Pond range and test kits, we strongly believe they are the best liquid test kits on the market, we use them in-store and have sold many over the years. Last year we have began stocking more of their fantastic ranges including their Pro-f food range and Aquarium range of water treatments.

“I Just wanted to say thank you for the help with bacterial issues I had in my pond. I can happily say that the mouth rot of one fish and the fin rot of two others has cleared up to near perfection now. I have been really impressed with the service from your technical team. I have already recommended online that people ask NT Labs about their products and recommended usage.”

Your Probiotic food is absolutely brilliant! I bought twenty one 1 year old Japanese Koi via a fish farm in Ogata, Japan about 3 years ago. I’ve been feeding them on Probiotic and Probiotic Growth in the summer months. Some of are now 2ft in length and of superior quality. It’s not cheap, but you get what you pay for.

I have used many products for the eradication of aiptasia over the last 15 years. Often with poor results. After purchasing the Anti-Aiptasia, I was astonished with the results! Absolutely fantastic and not like the competitors which normally contains some form of hydroxide. I would highly recommend NT Labs Anti-Aiptasia. This is arguably the best in the market!

I work at a pet store in Durban (South Africa) and have had the best results with my salt water aquariums that I have EVER seen. I have been in the industry for about 10 years now and seriously recommend the products supplied by NT Labs. All our customers that have used anti-aiptasia swear by this product and have said that it over rules every other product out there. Highly recommended.

"I called your offices for support and was put in touch with one of your Aquatic Biologists. He has been incredibly helpful... Without your help, my fish would be suffering and I might have had to stop keeping Koi. I cannot recommend your products, or staff, enough."
