I wanted to know if these fishes will be OK with a 20 gallon tank. The tank has the eclipse 2 filter with heater and everything.

4 dwarf puffer fishes
3 Otocinclus.

Ofcourse it will be heavily planted. Any recommendations for plants? I read that java moss is good for the puffers.
how can you sex the puffers if bought as juveniles.

I m making a java program where I have to write to a file- after reading from an input file. When I try to run it- it seems to not write most of the lines to the output file. When I try printing to the screen instead- it works perfectly.

Here s some of the code (some bits left out):

input = new FileInputStream(args[0]);
DataInputStream in = new DataInputStream(input);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String line;

while ((line = br.readLine()) != null) {
if(args.length == 2) {
FileOutputStream output = new FileOutputStream(args[1]);
printOutputFile(valid- type- line- output);
}
else{
printOutputScreen(valid- type- line);
}
}

public static void printOutputFile(boolean valid- String type- String line- FileOutputStream output) {
if(valid == true)
new PrintStream(output).print(line + " asdf");
else
new PrintStream(output).print(line + "blah");
}

Everything else is working. Help please!
PS. Yahoo cut off my print line but it s right.
