Scroob the Comet Goldfish
After a few failed attempts with fish in my 10g (mostly due to adding sick fish to the tank) I put in two small comet goldfish, with plans to move them to larger tanks as they got bigger. The larger of the two died but the smaller one is thriving in the 10g. He is alone (not sure if he is male or female but we call him a he). He eats well and is slowly growing. He started off about 1 inch long (not including tail) and is now about 1.5 inches (not including tail). He is about as big as his tankmate was when we first got them. My husband has named him Scroob (Spaceballs anyone?)

He eats a rather varied diet. He gets his goldfish crisps almost every day but a few times a week I give him something different. He gets bloodworms, brine shrimp, algae wafers, and fresh veggies. There are also pond snails in the tank and I've seen him picking off a few really tiny ones off the glass a few times. Anything else I can be providing?

Water conditions are wonderful. This is the first time I've ever fully cycled a tank and it was cycled before he ever got put in the tank. I keep an eye on ammonia, nitrite, nitrate, and pH and everything is doing great. Ammonia is always 0 (though a few times after cycle was complete I've gotten a small amount of ammonia. About 0.5, but it would go away within the week) Nitrite is always 0 and Nitrates never get above 20 as I do weekly water changes. I use API Stress Coat for water changes and I also add API Stress Zyme to the tank every week. The tank has some driftwood (unfortunately I used new wood and the water turned the color of tea.) and some live plants and a few artificial plants. I plan to switch out the artificial plants for live ones as soon as I get a better light, though I might wait to get a bigger tank before getting the new plants. Temperature is room temperature which in this house is around 70-72.

I'm not sure when I'm going to be able to get a larger tank as we are not going to be moving as soon as we thought we were. It might be a few months. He is only 1.5 inches long (not including tail) so how long do you think he'll be able to be healthy in a 10g with weekly 2 gallon water changes?

And I suppose the point of this post is to ask if there is anything else I can be doing for him to make sure he is healthy and happy? (other than getting him a bigger tank) I was thinking of getting another small 1 inch comet to be with him.

Okay first, do NOT get another comet until you have room for both of them. Room for 2 comets would be something around 180 gallons. So don't dig yourself a bigger hole just yet ;)

You might find it more convenient (and fun) to move the goldfish into a small pond if you have any backyard space... you don't even have to dig... a lot of people keep juvie comets in those big rubbermaid feeding troughs.

The 10g should be okay for a month or two, just keep an eye on the ammonia. Anything above .25 is bad news. I have kept single baby fancies in a 5g and they fouled the water up wayyy faster than I ever thought they would. Like in 2 days. So heads up! I would say you can keep the comet in the 10g up til the point where you can't keep the ammonia below .25 for more than 2 days w/o water change. After that, you can buy yourself more time by housing him in a rubbermaid storage bin.

Oh! And about diet... everything looks good, however you might want to change up the flakes for some pelleted food that won't swell in his stomach and cause bloating. Hikari is a great brand, as in New Life Spectrum.

Wow! I never thought of makeing a plastic tub into a goldfish pond! Too bad that wouldn't work at my house, too many cats lol!:lol:

Just as a little update. Scroob is still in his 10 gallon. He's doing wonderfully and is growing. He is now approaching 2.5 inches including tail. Unfortunately, this week, my mother in law decided she was going to add fish to the tank. My sister in law has a 10g with live bearers, mostly platies and her tank has become overrun with fish. So two days ago my mother in law says to me, "Oh by the way, OUR (I put emphasis on this because she calls it our tank even though its MY tank) tank will have some new babies in it soon. I'm bringing home some of your sister in laws fish because her tank doesn't have any more room."

I told her that my tank was full as it is and she laughed and said there was plenty of room since I only had one fish in it. I didn't want to get into an argument with her because she always thinks she knows more than I do about fishkeeping (she used to breed fish a long time ago. We have VERY different keeping styles).

So sure enough, last night, I come home to find a bag floating in my tank. It contains 2 adult red wag platies and two younger red wags. 3 males and 1 female. One male is obviously in bad shape. He doesn't swim much and he just looks old and sickly. Another male has clamped fins most of the time and the other two look fine. I was so furious but I held my tongue. I think at this point I'm just going to have to go ahead and move Scroob to his indoor tub pond now. I have plans to set him up in one in the next few days. It will be 15 gallons for now and I will get a larger tub in the next month or so. The filter is rated for a 30 gallon tank.

Anything I can do to make sure he survives the change to the new tub pond and the inevitable cycle process he will have to go through? I don't think he'll survive in the 10g with these new fish. They just don't seem healthy to me, whereas Scroob looks wonderful. I've grown attached to this little comet and I don't want to lose him. I'm still mad at my mother in law for just assuming I'd be okay with taking in these sickly fish.

Also! Should I treat his new tub pond with anything for disease since he has been exposed to these unhealthy looking fish? There is nothing obvious as far as disease, but they just strike me as unhealthy fish.
