After a nice 95% water change last night, I took some photos of the fishies! Here's the 75 gallon tank (85 gallon capacity with sump).
Clover (male red/white ryukin)
Luca (male white butterfly telescope)
Felix (male red/white butterfly telescope)
Now for a little update about them... Clover has been an occasional bottom sitter for a long time now, which
is sometimes common in older and larger fish like him, so I don't worry
too much about it.
Ever since Clover was tiny he's been prone to fin congestion (red
blotches) in his tail fin despite good water quality, and I wonder if that's related in some way to
the bottom sitting. A goldfish breeder on Goldfish Keepers Forum said
fish with longer fins can sometimes have chronic fin congestion which
leads to bottom sitting later in their lives. So that could explain his
bottom sitting habit. Anyways, I'm getting a little off topic here! Last week I noticed him upside down a quite a
bit too. Not floaty, just resting upside down near the bottom of the tank. It was so discouraging to see, especially after recently
having to euthanize Callisto for her chronic swim bladder problems. Clover's
abdomen is nice and firm, like it should be, so that's good. I'm not
sure why he would be going upside down, but I decided to fast him for a
while to see if that would help. And it did; after a couple days of
fasting, he always remained upright. Then I started feeding him a small
amount of Saki-Hikari pellets, and again, he was back upside
down occasionally. So I guess maybe he just can't handle those pellets
anymore. Now I've switched him to only Repashy gel food (plus bloodworms a
few times a week), and he's doing better. Maybe only Luca and Felix
can have the Saki pellets from now on, and that's fine. It just makes
feeding them a hassle, because I have to isolate Clover in a colander
while the other guys eat. Speaking of those two, they're doing great
and growing fast! They love to root through the sand in search of food,
especially Felix! I've been hand-feeding all of them a lot lately, and even shy Clover has been much more outgoing and friendly than usual.
I usually do 90% water changes, but last night I did a 95% change. I had to remove the fish to a big bucket to drain the tank that much, and I kept them in the bucket for about 45 minutes after refilling the tank to let everything settle before putting them back in. I think they actually liked that better than being in the tank while it was filling, so maybe I'll always do that from now on. In other news, I'm still trying to teach them their names, but I don't think they've caught on yet. That's all for now!
