Troubleshooting

My culture has slowed down

Work through the usual causes in order, from food and moisture to air, age and mites. Each ending says what to do and where the advice comes from.

Start from what you see

My springtail culture has slowed down or is crashing

Questions

  1. Question 1

    Is there fuzzy or slimy mold, or leftover food that has gone off?

    Look at the food spot and the surface of the medium.

  2. Question 1

    Is the medium dry, cracked or pulling away from the cup?

  3. Question 1

    Is there standing water, or does the medium look soaked and soupy?

  4. Question 1

    Is the lid fully sealed with no vent, and rarely opened?

  5. Question 1

    Is the culture about six months old or older?

  6. Question 1

    Do you see tiny moving specks that are not springtails on the food or walls?

    Springtails spring away when disturbed. Look for specks that behave differently.

Endings

Likely cause

Overfeeding and mold

Act this week How sure: High

The answers point at one clear cause.

What to do

Mold in a clay culture is usually caused by overfeeding. The usual fix is to stop feeding until it clears, or to scrape aggressive mold off the clay surface. Anecdotal 1
Warning Every seller gives the same rule about amount. Give only what the springtails can eat before the food rots or molds. Hobby consensus 1–4
Warning In the worst case, too much yeast can kill a culture by creating a high concentration of carbon dioxide. Anecdotal 1

Easy to confuse with

A culture that is just old, which also slows down.

Guides that help

Likely cause

The medium has dried out

Act this week How sure: Moderate

Several causes fit. This is the most common one.

What to do

Water the clay with one or two drops from a pipette, so you do not get it too wet by accident. Anecdotal 5
Keep clay damp but not wet. A little clay should stick to a finger when you touch it, and there must be no standing water. Hobby consensus 1, 4, 5
Water the culture once a week or as needed. Anecdotal 6
Feed every 3 to 7 days and keep the soil moist. Moist soil is best, not sopping wet. Anecdotal 2

Likely cause

The medium is too wet

Act this week How sure: Moderate

Several causes fit. This is the most common one.

What to do

Warning A common misconception is that springtails need very wet clay. Very wet clay fully absorbs food powder and goes bad much faster. Anecdotal 5
Keep clay damp but not wet. A little clay should stick to a finger when you touch it, and there must be no standing water. Hobby consensus 1, 4, 5
Feed every 3 to 7 days and keep the soil moist. Moist soil is best, not sopping wet. Anecdotal 2

Guides that help

Likely cause

Stale air in a sealed container

Act this week How sure: Moderate

Several causes fit. This is the most common one.

What to do

MI Beneficials keeps its cultures airtight and opens the lid every 2 to 3 days for an air exchange. It says springtails slow down from too little oxygen and too much carbon dioxide when the lid stays shut. Anecdotal 4
Springtails US adds a small vent covered with 35 micron ultrafine mesh. That gives enough air to prevent a dangerous build up of gas without drying the culture. Anecdotal 2, 7

Easy to confuse with

Overfeeding, which can also raise carbon dioxide.

Guides that help

Likely cause

An old culture that has run its course

Keep watching How sure: Moderate

Several causes fit. This is the most common one.

What to do

Frog and Frond finds clay cultures slowly decline and keeping an old one stops making sense around or after 6 months, though some keepers use them past a year or two. Springtails US says a plaster culture lasts 6 months to a year or more. Hobby consensus 1, 6
When inoculating a new container, take only a half to two thirds of the springtails and leave the rest to keep breeding. Do not tap them all out, or the source culture stalls while the new one gets going. Anecdotal 4

Guides that help

Likely cause

Mites in the culture

Act this week How sure: Moderate

Several causes fit. This is the most common one.

What to do

Sellers disagree about mites. NEHERP says mixed media cultures are much more likely to get mites than charcoal cultures. Frog and Frond says clay cultures are less likely to get mites than charcoal cultures. Anecdotal 1, 8
No source read for this site gives a tested way to remove mites from an established culture. The sellers focus on keeping them out with mesh, sterile food and substrate, and the choice of medium. Unknown Open question How do you clear mites from an established springtail culture?

Guides that help

Likely cause

The set-up may not suit the species

Keep watching How sure: Low

A best guess. Check the look-alike before you act.

What to do

Some springtails have only been proven to culture on soil, or do much better on soil than on other media. Anecdotal 2
Springtails US says arid springtails need care unlike any other springtail commonly kept, though it is still quite simple. Anecdotal 9
Mimic the environment where the springtails were found as closely as you can. Once you have had success, you can experiment with new set-ups. Anecdotal 10
