I'm starting to think clearly again. I haven't taken any pain med's for a few days.
Back to the skinny clowns-
The skinny clown in the q-tank is showing interest in food again. She's not as lethargic anymore either. I'm thinking of putting her back in the refugium.
I really don't think this is a parasitic problem and I still have many doubts that the snails are hosting parasites. I've been breeding these snails for a few years now. I think I'd have more skinny clowns if the snails were infected. Let's remember, I do have 50 clown loaches, all sharing the same waters and eating the same snails.
For review-
I purchased these clowns as a group of 5- 6" clowns from a seller on Aquabid. 2 of them I euthenized because of severe emaciation, 2 are skinny, and 1 is doing fine. They weren't skinny when I got them. I don't remember how much they were eating when I got them. I got them in October of 2005. I was using my 95g for the quarantine period and they didn't showed signs of illness, so I kept them q'd for only about 10 days.
In December of 2005, I got a batch of baby bristlenose Pleco's and a large male Boesemani Rainbowfish from a local breeder. A few of the pleco's died in the quarantine tank the 1st night I got them, I panicked, then for some dumb reason I moved them to my main tanks.
After this move, most of my fish started flashing. I didn't hesitate to treat my main tanks for parasites. I put the Male Boesemani in the main tanks also because I was treating the tanks anyway. I didn't see anything disease outbreaks, so I stopped treatment after about 2 weeks. About a month later, some of my Boesemani Rainbowfish were having Columnaris problems and 2 of my clowns got real skinny. I quarantine all the sick fish.
After a few grueling weeks in quarantine, I euthenized the 2 very emaciated clowns. They would not eat anything.
(The Boesemani rainbowfish were getting better, so I moved some back to the main tanks, but I kept the 2 worst infected Boes quarantined for about 6 months, then I moved them to the refugium for another 6 months. I put them in back in the main tanks just a few weeks ago.)
Some of my clowns were breaking out with black spots and 3 more clowns were showing signs of skinny. Bear with me now. I've discussed in other threads about how I think TDS drops from water changes causes black spots and osmotic shock. I've also recently found out that excess iron in the water column will greatly increase baterial populations. I'm thinking mild osmotic shock & the Iron Fertilizers I was dosing (for the plants) triggered the Columnaris problems with the Boesemani and caused an internal bacterial infection to the finicky skinny clown loaches.
So why did my clown get skinny again? Fact- The fungus (columnaris?) it had on it's barbel's kept it from eating. What caused this? Probably a water quality issue. My water changes are smaller during the cold Winter months because the water heater get's cold quick. I should reduce feeding, but I haven't. I just checked the nitrates and they are higher than normal right now. I want them to be about 15, but it is in the 30-40 range. Not a wonder.
I need to increase the water change frequency to atleast 2x per week during when the weather is cold like this.
Also I really need to get these skinny clowns to start eating prepared foods.
So here's my plan-
I'll go shopping Today for some fresh foods so I can make a small batch of Martin's Loach Recipe with the gelatine. I'll keep trying new recipes and hopefully I find one she likes. If she does start eating this, then I'll slowly incorporate some staple foods into the recipe.
The other skinny clown in the main tank is doing so so. She's a little thinner, but she's starting to get use to competing for food with the others. I don't think she's eating the staple foods, but she's getting a share of the clams and shrimp I feed them.
