Any new haits or istlanum?

  • We are currently upgrading MFK. thanks! -neo
Looks like you got some oak leaves in the bottom there duanes. Nice touch! I think the best thing for young hait bloat is to keep the water changes big and often. Water temp in the 80s is good. Once fish get older, one or two odos with no other fish is what has helped me. Stress is a big factor with hait bloat, as many here have said before.
 
I'm guessing there were around 500 fry in all, whenever I would remove some, a bunch of smaller ones would come out of the woodwork, I hadn't noticed before.
The leaves worked well for a whille Darth, but when the fry appeared, the parents would bury them, or tear them up.
My normal routine is to change about 20% every other day, even with those water changes, if the temp dropped a little (to 80 or below)I'd see a few bloat up.
85 and above seems to work best.

I had to remove the male after the fry ate a gaping whole in his side

He's almost back to normal now.
And Darth, a group of the fry ended up near you, in Statham.
 
I'd like to know how fast your male hait grew duanes. Mine is a real slow grower. He is solo in a 75 gallon for now. He eats a lot. I do one 60% water-change each week. I have heard variable info on growth rates for haits.
 
You sure it wasn't the female that to the male? heheh
 
I came down in the morning, and the fry had him pinned up against a log. He wasn't resisting, and they were chowing down, I was amazed. I should have taken a quick pic, but wanted him put of there asap.
The fry have left the female alone, other than a little chewing on her fins, but they would swarm the male.
As you know, I have had plenty of bloat issues over the last couple years, and I ended up getting the male as a 10+" adult. I got the female as a 2" juvie at the 2006 ACA, she grew to 10" in about a year.

I'm beginning to believe that temp is the most important factor in keeping the immune system of the young from deteriorating.
All my water perameters matched collection data. In the past, I tried the low protein food regime, tried adding salt, and nothing seemed to prevent the young from kicking the bucket. Then re-reading the collection data from Louiselle(BB), Stalsberg and deRham(oh island in the sun) all temps where the were caught Odo, ranged from mid 80s to almost 100'F.
I also remembered teaching my kids to snorkle in a secluded cove on St Maartin (a nearby island), and the water (even with an outlet to the Atlantic) was like hot bath water, duh, what took me so long to remember and wake up!
I have been checking with some of the people who ended up with my fry,(including Sooner) after I got a call from 1 person who said all his were dying, his temp was @80. All others who I've communicated with that have maintained 84'F and above seem to have been successful. In fact one guy in Chicago says his temps hover just below 90 and lost only 1 out of 12, and that was, just after he received them.
I don't believe these temps are required for adults because they move to deeper water, but because fry would tend to hang out in shallows, where water is warmest, I believe there must be a developmental optimum range. This does not negate other factors of stress, or nutrition, but any species that comes and has evoled in a very stable environment, may be more sensitive slight variation.
Anyway, that's my theory until it falls apart, and I'll quit blathering.

I had a heater go bad with my haits when they were ~2" or so... water temp spiked at about 94-95F and they were fine. VERY hungry and VERY active, but fine. The large bristlenose in the tank didn't do quite as well and ended up as a stripped bare skeleton in a very short period of time! You may be right on the temp. My 2 adults are kept at around 82F.
 
Last summer my inline heater spiked enough to do this to the PVC, the day before the pipe was straight. The adult haits were none less for the wear.

It was the inline heater the stopped working about week ago overnight, because it was below zero outside, and the basement old. Basement air temp barely remained 50, and the water temp dropped fairly quicky to 70s, the adults were fine, but @ 40 1" fry died.
The day before they were lively and eating like pigs.

Maybe I need to turn the heat up on my male hait a little and he will grow faster? He is used to about 82-84F.
 
I have two big female Haitiensis and two males at 8" and 6". I only have one Istlanum and is only 4" right now. I took pics of the Istlanum a few days ago. I'll try to dowload it tonight and post it.
 
Great. Look forward to seeing the pics.
