Nicaragua Cichlid aka Cichlasoma nicaraguensis

Friday, September 21st, 2007

I’ve kept these Cichlids twenty years ago, and I’ve been trying to find a pair since, these cichlids have spectacular colours, especially when breeding. I’ve not seen them in the shops, and in the late 80s, was lucky to have three females and one male - long since gone.

I was lucky to find, that a local cichlid breeder, was giving up a very young pair. I put them in a quarantine tank, with a pair of Geophagus proximus, I like to quarantine all new arrivals into the fish house, for four weeks before moving them into breeding tanks. I picked these up on the 9th September, and I noticed the Geos were being bashed to hell, only to notice in a plant pot, fry a few days off from free swimming.

The unusual thing about the Nicaragua Cichlid Cichlasoma nicaraguensis is that the eggs they lay, are not adhesive, and roll-around the floor. I assume so they can move them from nest to nest, unlike most cichlids, that use a surface to spawn on, and their eggs are adhesive.

Whoops - and the LifeGard FB900 doesn’t need fluidzing anymore!

Thursday, September 6th, 2007

As previously hinted in a recent posting, I’ve been having difficulties fludizing my LifeGard FB900, the instructions state that a 600lph powerhead should be ample to do this, but I’ve found the back-pressure caused by the sand in the filter affects the powerheads performance, and its not up to the job, I’ve tried a Hagen 301, Maxijet 600, and a Juwel 1000lph powerhead to no avail.

I’ve emailed Pentair in the US, and wait a response, I think I’m going to have to use an Eheim pond pump, but before I had a chance to do this, I left the LifeGard FB900 in my porch, rather than leaving outside, I didn’t want anyone to steal or frost to damage it.

and then my partner knocked it over this morning and smashed it, it had media and water in it, as she was trying to grab the kittens!

I think you’ve got to laugh sometimes, although, I was not too happy this morn!

So I’m trying to obtain another one, which is proving difficult at present!

UPDATE I managed to obtain another, I almost had two! One direct from German Aquatic distributor, and then another new one appeared on eBay, a tenner cheaper!

Wild Male Angel Treatment

Thursday, July 26th, 2007

I’ve been treating with API Melafix, but I think I’m going to have to change to something stronger. The ulcer is both sides of the body in the same position.

Any ideas, email me

Here is a picture of the fish. Please click the image to obtain a high resolution version.

Aequidens rivulatus aka Green Terror/Gold Saum

Sunday, July 8th, 2007

“Does exactly what it says on the tin” to repeat that well known UK phrase.

The female Green Terror has killed my Rusty Pleco (L077). I’ve had this pleco for about four years, when purchased it had blue eyes, in the last three years has taken on the more rusty colouration.

I purchased a pair of Green Terrors Aequidens rivulatus, from a local fishkeeper, which had difficulties with the male and female, male almost killing the female, and this resulted in a very shy female, unlike the male, which “charges” the tank everytime you go near it. I’ve had them seperated for four months, and the female has slowly been happier, not as shy, sharing the tank, was a Rusty pleco, which I thought was Indestructible (a bit like Captain Scarlet!), she’s proved me wrong! I don’t know why she flipped!

I’m hoping to breed them in the future, If I can get them together.

I like the Aequidens group of South/Central American Cichlids, and many years ago had some Aequidens Pulcher Blue Acaras (I think the latin name has changed since!), which is similiar to the Green Terror, but maybe not a killer!

Under Pressure!

Wednesday, June 27th, 2007

I’ve been using two Hailea piston based, ACO-308 and ACO-208 air-pumps to provide air in the fish house, using a 22mm ring main “air-reservoir”. I purchased the first ACO-208 in September 2005, and when my generic 40lpm “Hi-Blow” failed when I moved just under tweleve months ago, purchased another larger ACO-308 to add to the “air-reservoir”. I’ve never really been happy with the amount of air, especially in the deeper tanks (> 2 foot). I switched to Hailea because they were cheaper to run, but I’ve since found, they cannot deliver the pressure and are noisy, my master bedroom is above the fish house, and I can hear the pumps through the floor!

So I’ve recently purchased a Japanese Secoh SLL-50, but I still wasn’t getting the required pressure required. After consultation with a DIY expert, we will call him SimonL at work, he mentioned that I needed to use 15mm and 22mm inserts in the Speedfit piping, and also cut the pipe using a poly pipe cutter, not a hacksaw (I knew this bit, but I didn’t think it would really matter!). I borrowed SimonL’s poly pipe cutter to re-cut all lengths of pipe, and disappeared to ScrewFix to purchase some pipe inserts (well I didn’t know, it didn’t say it on the pack!), re-assembled the ring main “air-reservoir” and like magic plenty of pressure!

Re-visited the fish house, 30 minutes later to find no air! I thought the ring main had failed, it wasn’t the ring main but the back-pressure on the diaphragms in the Secoh SLL-50, that had failed! I’d forgotten to open the bleed valve on the ring main, which usually feeds into a large volume of water, that I use to change in the tanks. So I purchased a Service Kit from KoiKit by JustKoi. Fantastic service, the service kit arrived promptly, Secoh pump serviced, diaphragms replaced, and to prevent this happening again I purchased Pressure Relief Valve and Pressure Guage Assembley from partsandpumps.co.uk, again Fantastic Customer Service, tell David I sent you!

This pressure relief valve is a pump protection device against over pressurisation. The valve will safely vent off any pressure over 0.2 Bar, and it’s been doing that!

I think I’ve got too much air now! But the leaks in the “air-reservoir” are fixed - Thanks SimonL

Microrasbora erythromicron fry picture

Thursday, May 31st, 2007

I think this is a better photograph, these fry, are very very small approx 5mm, very difficult to see with the naked eye.

Microrasbora erythromicron spawn, fry hatch.

Wednesday, May 30th, 2007

At the end of March, a label on a tank in a local pet shop caught my attention to some fish called Galaxy Rasbora, which later turned-out to be Microrasbora erythromicron., common names could be Crossbanded or Emerald Dwarf Rasbora.

I purchased these little fish (25mm), knowing they were Microrasbora erythromicron in a hope to breed them, I don’t think these are rare, but at present probably less common than the famous Galaxy Rasbora.

I checked the tank this evening, and I have a few fry from the trio.

I’m ecstatic, I haven’t felt like this since, breeding my first guppies, and that’s a long time ago!

Maybe I’ll now find that elusive Galaxy Rasbora, and give them the same “luving”, in a hope to breed them.

It’s taken over 400 shots to get the following pictures, glad I’ve got a digital camera. These were taken on the digital SLR, I’m running back in with the other camera, it has a better macro function (and it’s cheaper if it falls in the tank!)

I’ve been pre-occupied with DIY on the house, but I’ve finally received the additional stands, to add six new tanks to the fish house.

Nannacara adoketa have started to spawn

Friday, May 11th, 2007

My suspicions have been confirmed two out of the five Nannacara adoketa in the quarantine tank have paired-off and to my astonishment have started to spawn this evening. Male and female fish confirmed, as pedicted in earlier pictures posted here.

This is a young pair, and this is their first spawning, I’m not too sure how viable this spawning will be, with three other N.adoketa in the tank, plus a Bristlenose catfish, and the waters wrong, ph 8! But I wanted to get these pictures on the blog, quickly.
