can siamese fighting fish live in a community tankWithin that decade, a German breeder created the “deltatail” characterised by its broader, triangular fins. Bettas also are plagued by the pH of the water: a impartial pH of 7. 0 is right, but a little higher levels are tolerable. Due to their labyrinth organ, bettas can endure low oxygen levels, but cannot continue to exist for long in unmaintained aquaria, as poor water nice makes all tropical fish more prone to diseases like fin rot. Thus, notwithstanding the betta’s sought after tolerance of still water, a mechanical filter is needful for their long run health and sturdiness. Similarly, live aquatic plants supply a supplemental source of filtration, in addition to crucial enrichment to the betta.
