New Plants on the Bed

It has been raining all day over the weekend so nothing much can be done outside. It was a very lazy weekend for me. I planned to change the water in the tank but decided later that it is not necessary. The fish, despite all the symptoms, are still swimming happily with no sign of dying. So I figured, if they are happy I should leave them alone... at least if they die, they die in happiness....yes.

The seeds, well only the cucumber sprouted. The parsley seeds just rot in the pot so I threw it away. The cucumber is growing very fast. For a first few days there was like nothing happening and then suddenly one morning there was 2 inches of sprout already in the pot. The next day it double the length and by Saturday, got to 6 inches. So I moved it all including the pot into the grow bed. I don't want to the disturb the new roots so until it established itself with many more leaves I will leave it in the pot.

The fish is used to the new diet now. However since the pellet size is smaller than the previous one, they need to eat more so the food is depleting pretty fast. I notice some changes in the plants. The chilli I got  from a project by my wife's student a few weeks back now has slowly change its colour to green. It was yellow before and doesn't look it is going to live. So, positive result after changing the fish's diet so far. Hopefully this is not just a placebo effect....further observation will be done until I am satisfied that the food is actually playing a role here.

And finally, my wife bought a bunch of Selom (Water Dropwort/ Water Parsley) from the wet market. It was pretty hard to get it so I'm very happy. After sorting I managed to get a few cutting which already have some roots. I planted it around the mint bush. Hopefully it will grow well and provide us with endless supply of fresh leafy goodness.

4th Month Update

Today, my system reached 4 months old. A Tilapia died yesterday, one of the bigger ones, for no apparent reason. I was worried about my Koi because I noticed what seems to be haemorrhaging near the gill area. So I googled and found what could be a VHS infection. VHS or Viral Hemorrhagic Septicemia is a viral infection that affect fresh water fish and there is no remedy for it yet. Infected fish can only be isolated and monitored as there is a chance of survival. From wikipedia, the symptoms of VHS are haemorrhaging to of internal organs skin and muscle. Some fish shows NO EXTERNAL SYMPTOMS. Others might show sign of infection from bulging eyes, bloated abdomens, bruised looking reddish tints to the eyes, skin, gills and fins. This is actually how most fish especially Tilapia in my tank look like.

Look at the bulging eye, bruised/ reddish around it

Recalling the dead Koi last week, there is a yellow mucus on the snout and bright red gill...found out that that is a secondary infection caused by Septicemia. The bright red gill is also found on the Koi I inspected last Saturday. This is really sad. I think I brought in the infection from the newly bought fish as the virus can be transmitted through infected water. I just pour in the water from the bag into my tank. BIG mistake and lesson learned. Next weekend I will clean the tank as much as I can with bleach and hopefully the remaining fish will survive the ordeal. This would also mean killing the bacteria in the grow bed.....dilemma!

Anyway, on the growbed things are going well for the mint. It is growing wild. Look at the picture and compare it from my last post. The matured leaves are almost 3 finger size wide!

The seeds however haven't germinate at all so I made a new plan. Checkout below picture:

I re-sown the parsley but not the coriander and rosemary. On the other pot is cucumber seeds, I think from the Japanese variety. The water is fish water from the tank. I found that the LECA has a very excellent water pulling efffect (can't remember the correct term :o) ) so the seeds will be kept moist with that little water at the base. I put this on the window sill at my kitchen so it can get fresh air and light. Give this a week and see what happen.

One more thing, since I'm having a little problem with iron deficiency  in the growbed, I decided to change the food for the fish! AHA! surprise surprise. I thought by feeding the fish with food that has high iron content should also benefit the plant from the leftovers. So I looked for such feed and found this:

Spirulina based fish food! Spirulina is know to have high iron content, also magnesium among others. Price per kg is RM23 which should last for a month, give and take. I just started the new diet yesterday. Still too early for anything but I'm really eager to see if this will work.

Another Death

Last Thursday my wife called me as I was about to leave my office around 6.15pm. She told me one of the fish is dead. "A white fish" as she told me so I thought it must be of of those tilapia. When I got home my son already fished it out of the tank, it has been discoloured and dry a bit and does look like a tilapia. On closer inspection I found the mouth does not look like a tilapia and there is a yellow spot on the snout. I don't recall any of my tilapia has yellow spot there. It was dark so I just checked the tank for any more dead fish as well as any thing unusual or out of place. All seems find so I dismissed the case as another "normal" death.

Saturday morning I did a head count on the fish and found 8 tilapias still swimming happily. Well the dead fish is not a tilapia after all. It was one of my Koi. The dead one is the golden white Koi. Cause of death is still unknown. Will look for replacement Koi as this fish add colours to the tank.

In another uninteresting news, the seeds I sown haven't show any positive result, yet. I will try another plant this weekend if the condition were not improved.
