Cloudy water – some animals
seem to cloud their water much faster than others. Fiddler
crabs for example. Simply increase the number of partial
water changes. Usually two a week is more than enough for
Algae – Algae is going to want to
grow in your bowl, especially if you have animals and plants
that do not require a lot of water changes and if you globe
is getting a lot of direct sunlight. But don’t worry,
Algae can be controlled by a number of ways.
• Snails – Trumpet, rams horn and mystery
snails will eat algae
• Plants such as Arachis and Hornwort, while great
oxygenators also secret a chemical that specifically fights
• Reposition your globe, even for just a few weeks
to where it gets less sun
Death of animals and plants
Too many animals can over burden a globe’s
natural filtration ability causing the entire population
to die off quickly from ammonia poisoning.
The wrong types of animals for the globe can
have dire effects. For example, 4 zebra danios will do well
in one of our large globes but put 4 Tiger Barbs of equal
size in the same size globe and they will probably fight
to only one is left. Another example are goldfish which
really don’t do well in any kind of bowl. They produce
so much ammonia that daily water changes would be necessary.
Temperature requirements vary from animal to
animal and should definitely be considered when chosen your
pet. The charts below can help.
Overfeeding – again, be aware of the damage
caused by uneaten food.
Lack of oxygen, good oxygenator plants are Anacharis
and Hornwort. Also globes should not be filled too fare
above the half way mark to allow for a greater amount of
water surface to interact with air.
Plants, even water plants need a certain amount
of light and usually near any window will do fine for any
of the plants mentioned . Plants need food as well and will
do best when there is some form of animal producing CO2
and ammonia (plant food).
Scum, Scum buildup can
develop on top of water and sides of bowl. Clean the bowl
with a natural sponge or aquarium sponge cleaner, NO SOAP!
