20 Gallon Long Stocking Ideas

Hello,

I have a 20 gallon long tank. I currently had 8 Zebra Danio Glofish, 8 Neon Tetras, 1 Dwarf Gourami, 4 Cory Cats, 4 Amano Shrimp.

The tank was started 3 months ago, tank fully cycled, but I have lost 3 Zebra Danio Glofish in past month:

3rd Zebra Danio to exhibit this Illness - Any Ideas what it is

I think the glofish are dying from genetic issues, because whatever is killing them isn't spreading. I am done with glofish and want to add a new species, any ideas of a good community fish that's peaceful, possibly schools for my tank?

How are guppies?

I would suggest adding more cory cats so that you have at least six. Corys are schooling fish and need to be in groups. Sorry, I can't tell you anything about guppies. I have no experience with them.

I am partial to cories. What type of cories do you have?

Yes I was thinking of adding at least one more cory to have a total of 5. I have all Albino cories, love their white look on the gravel, and their eye balls freak out my kids lol.

After doing research I read that guppies are bad to keep with Gourami due to nipping so I will look elsewhere, possibly Cherry Barbs.

Still going nuts trying to figure out whats wrong with my danios, thinking maybe parasites.

Sorry, I can't help with danios. I've never had them.

Well just lost my 3rd Danio, and now I can see another Danio has Callumanus Worms, and another is swimming 15 degrees on its side which is a sign of Callumanus Worms. So I have a god damn infection. Now doing research on how to hopefully eradicate the worms and save the fish.

Sorry you're having problems with your glofish! I don't know how to help you, since I've never had danios.

I would suggest either getting 1 more cory (I strongly recommend, those corys should be in a bigger group) or getting 2 platies. I think that you would be overstocked if you picked anything else. My rule of thumb is 12 square inches of surface area for 1 inch of fish. That means in a 20 gallon long you shouldn't have more than 30 inches of fish. So, hence, the 1 more albino cory or 2 platies.

For the reasons stated above, I wouldn't get cherry barbs because they need to be in groups of at least 6, and they each get around roughly 2 inches big when full grown. That would be 12 inches of fish which means you would have 38 inches of fish in your tank! That's too much.

Another thought I had was that you could get snails or more shrimp. I don't count those as taking up space in the 12 square in. for 1 in. of fish rule because they don't produce a lot of waste.

Thank you. I decided to wait till I am 100% positive the infestation is over, but worried about how many fish I will loose in the meantime, I am reading Callumanus Worms are horrible and will kill most of your fish.

If I can deal with this worm issue, I agree I will first add one more Cory Cat to have 5 total. I will stop stocking Danios, and will start adding Platties when my Danio population hits 4 or less (which at the look of everything will be really soon, praying I don't loose my Cories and Gourami).

Sorry about your fish. That's horrible. Definitely let your fish recouperate from everything before adding new fish. You don't want to add new fish until you are sure your others are healthy. Losing that many fish in so short of time is pretty disheartening. Wishing you the best.
