I would really like to get another fish or two to put in my tank. I have live plants and am adding on as much as I can. The point of this is cleaner water, more hiding spots. So that's why I'm considering getting some mollies or guppies. I would definitely get ones that aren't fancy tail because I don't want a massacre in my tank. I'm also considering a pleco, not that it would interfere I don't think. Does anyone have any experience with placing these with male bettas? Or any other suggestions for some small fish that would be compatible? Thanks.
How long has the ten gallon been running with fish? What is the pH?
Mollies and guppies prefer hard alkaline water with pH between 7.4 and 8.0 and both of these species might find the long flowing fins of your betta an easy target (nipping).
Mollies need minimum of 20 gallons and males would not get along well in smaller tank, and females are almost inherently pregnant when purchased. This could lead to population explosion which could make maintaining water quality more difficult.
Were it me,, I might consider five or six glowlight tetra's, They stay small and are too quick for the betta ,and would not be as likely to begin nipping the fins of your betta.
Do be aware that the betta may not tolerate guest's in his enviornment and many are often best kept alonefor this reason.
Even the smallest Pleco would be unsuitable for a ten gallon tank with possible exception of LDA25 Pit bull pleco which fairs best in pH range of 6.8 to maybe 7.4. IMHO
Plecos produce considerable waste, and small tanks do not have dilution capabilities between water changes to accomodate these fish.
Otocinclus might work but only if the tank is well established with considerable algae ,which is this fishes primary food. These are sensitive fishes with respect to water quality and many of them are starving or sick when purchased.
Hope some of this helps.
