Recently Empty ~40g, need advice

Hey guys,

I don't usually post to this part of the forum, as I generally keep to the betta-specific section. :)

However, my goldfish recently passed away from flukes, and now I have a 38g tank that is empty. It also has .3% salt and Prazi Pro for flukes. Obviously I don't want to introduce any fish to this mess until I know it's safe. How would I go about doing this?

Should I try to save the cycle and just keep treating the tank? Or should I not risk it and nuke the tank (tear it down and give everything a good cleaning)?

If I do tear it down (which is what I'm leaning towards), I'm thinking of going with a fishless cycle using ammonia. Any advice there?

-38g tank
-Penguin Biowheel 350 filter (big for the tank size due to the goldfish)
-All-Glass Aquarium heater 200W (unused)
-Active airpump

Are you planning on planting live plants?

No live plants. Here:

-38g tank
-Penguin Biowheel 350 filter (I also have an unused Aqueon filter that is made for 40g)
-All-Glass Aquarium heater 200W (unused)
-Airpump
-Decor, all artificial

I also have an already established tank I can use to seed this one, if that helps.

I don't know how effective treating a tank for flukes is so I won't comment on that. Otherwise if you were going to have plants you could nuke the tank, set it up fill with water plants and start adding fish right away.

Without plants you are pretty much stuck with recycling the setup to be sure it is clear.

Alright that's what I was leaning towards anyway.

I'm looking to stock my tank as well...Have you (or anyone else) had any experience with gouramis?

Welcom to (this side of) the forum

Parasites require a host to survive, so simply leaving the tank running, but empty for a period of time, should take care of that. The bacteria in the filter will absolutely outlive the parasites, so you do not have to worry about losing the cycle. The same is true if you were inclined to administer a treatment on the tank. I see absolutely no reason to tear the tank down and start over.

The filter is of normal size for the tank, in my opinion and experience.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

Thanks. That makes sense, but I'd rather recycle it and have absolutely 0% chance of reinfection.

Suit yourself If you already have an established tank, then all you need to do is transfer some media to the other tanks filter and you will have your cycle.

I've got quite a bit of experience with gouramis. In your size tank, you have a few options. A single dwarf gourami, a group of honey gouramis, a pair or maybe even a trio of pearl gouramis (if the tank dimensions are good), or a single 3 spot gourami. There is also the moonlight gourami, of which I have no experience. If their temperament is is similar to the 3 spots, then just one. Based on the behavior of the one's I've seen, I strongly suspect that it is. Other not so common species are the banded and the thick lipped gourami. I don't have experience with them either, though I know people that do and they're not as aggressive as the three spots. Can't comment on conspecific aggression, as the people kept them singly, and I have not seen them in the store. Yet another option is the paradise fish - best described as half gourami and half betta. There are some small species too, like the sparkling gouramis - another group oriented species.

The group of honey gouramis seem intriguing. What would you recommend? (i.e. males:females, group size, heave VS light decor, filtration...the whole 9 haha)

And what about tank mates? Cardinal Tetras? Neons? Loch Ness Monster?

Thanks for all the help BTW!

I would start with a group of 3, and possibly get one or two more later. For tankmates - I would layer the tank with some fish that swim in the top half, some fish that swim in the bottom half, and some bottom dwellers. That's pretty much the standard way to stock a tank - you don't want all the fish to occupy the same region of the tank. Cardinals tend to stay higher in the water, and neons tend to stay lower, for example. For bottom dwellers, I would look at either kuhli loaches or corys.

For filtration - I am a believer in big filtration, though that's not very popular on this forum.
