Dwarf Puffer, Pea Puffer
Many thanks to Jasandjules for the the following article: - Dwarf puffers - The little fish with BIG character
Dwarf puffers (dps) are a relatively new discovery, a few years ago when India started exporting more of their native fish to the States and Europe there were a few relatively obscure puffers about the size of a pea ( hence one of their trade names, the pea puffer).
They were originally assumed to be juvenile examples of already known puffers but it soon became clear this was not the case.
"Dps" reach an adult size of 1 inch, they have black eyes that turn blue when they are in the light
and can move independently (like Chameleons), they can open or close their tail fin depending if
they're stopping or going.
They will also 'curl' their tail which can indicate stress or illness but also just a way of
maneuverability. They also can be seen opening their mouths up wide, as if yawning.
Their spots/patches are different colours and shades, from bluish green to black and from light to dark.
They can also change how dark or faded their spots are, depending on their mood.
Determining the sex of dwarf puffers when they are young is very difficult but easy in adults.
The males have a dark line running down their belly ( as well as more yellow colouring on their bellies).
The vertical line on the males darkens with sexual maturity and during spawning.
The males also have lines or wrinkles behind/above their eyes that the females do not have.
The females body is also much rounder than the males.
Dwarf puffers are best when kept in a 20 gallon, 1 male and 2 females. The tank should be very heavily
planted so the dwarf puffers line of sight is constantly broken and they have hiding places.
This will greatly reduce the amount/ chance of aggressive behaviour. Dwarf puffers
do not need to
school so a single dp can be kept, there are also examples of people keeping 20 in a 20g ( very
very heavily planted) with few problems, but I wouldn't recommend it, especially if you are new to
Ideally dwarf puffers need about 3 gallons each.
As far as tank mates go, although there are a number of examples of people keeping
dwarf puffers in a community
tank, it is not recommended!
Otocinclus make excellent tank mates and very few people have had any problems at all with these
coexisting. Amano or ghost shrimp are another possibilty, but if the dwarf puffers
discover how tasty
they are then the peaceful coexistence comes to an end!!
It is probably a good idea, as with any non species tank, when dealing with varying levels of
aggression, to add the least
aggressive first ( obviously the oto in this case) to allow them to 'claim' territories first.
Dwarf puffers will eat frozen foods (bloodworms being the most common and popular amongst dp owners), live foods (
blackworms, brine shrimp, snails etc). They will not eat flake food or freeze dried as a rule,
if they do eat any flake food offered it should not be considered a staple diet!
Although dwarf puffers don't have the need for snails to blunt their teeth the way other puffers do
( most puffers have teeth that continue to grow and grow, like rabbits!), snails can still
form a large part of their diet and they will enjoy hunting them in their tank, they are
just more likely to suck the snails out of the shell as opposed to crunching down!
Dwarf puffers are quite hardy and will tolerate varying water conditions but obviously will do best,
as with any fish, in optimum water conditions. They do best at temperatures of 80/26 degrees with a ph of at least 7.
Dwarf puffers are 100% fresh water fish, they do not require any salt, unlike some other fresh water
puffers they do not require salt as they grow older, although they will tolerate small
increases in salinity they are at optimum health in pure fresh water. Dwarf puffers
are a very intelligent, interesting fish, they are very aware of 'outside' the tank,
and will spend as much time watching you as you do watching them.
Give them a try!!
thanks to Lexcy in Abbotsford, BC for all the following information:
These tiny puffers are imported from India. They are surprisingly hardy
fish and they are also know as pea puffers.
They are said to be semi aggressive, but I find they are a good community fish, as long
as you have a big enough tank.
Males have a brown vertical line on their belly , which can darken and fade. The females
don't have this. Dwarf puffers seem to eat bloodworms. If they
don't at first, then try little tiny pond snails and ghost shrimp. They stay tiny at about 3 cm and
don't eat your plants. They don't require any salt, but I do add a
little. These little guys do have a personality.
They eat right out of my fingers, if I hold the food semi in the water.
They see me when I'm near the tank and all swim up to see what I'm doing.
They are very cute fish.
