Το ξυλο πανεμορφο και πολυ χρησιμο σχημα για δισκους,
Δεν ξερω ομως αν φτανει ενα .... αλλα που να βαλεις και δευτερο ομως?
Φυλατο και για το μεγαλυτερο ενυδρειο που θα παρεις.
Οι πλατες μπορει να ομορφαινουν το ενυδρειο αλλα σου κοβουν λιτρα και τωρα χρειαζονται.
Εκφραζω τη διαμαρτυρια μου για τις θερμοκρασιες αφου η αρχη των απωλειων δειχνει την δυσκολια της διαβιωσης για τους καρδιναλιους.
Απο 29C ισον 2.5% απωλειες, εως και 31C ισον 25% απωλειες.
Ιδανικη θερμοκρασια για καρδιναλιους 24-28C
MATERIAL AND METHODS
Cardinal tetra of 0.07 ± 0.002 g (mean ± SD) were collected from forest streams (igarapιs) of the mid Rio Negro basin located in the municipality of Barcelos, Amazonas State. Fish were transported to the laboratory in Manaus, Amazonas, where they were kept in 500 L holding tanks supplied with stabilized temperature (25 ± 1oC) and aerated water, regularly fed with a commercial fish diet for at least 4 weeks prior to the experiments. Bioassays to establish tolerance limits to pH, temperature, ammonia and nitrite were performed in four 40-L test chambers equipped with an air compressor and a thermostat bath. Twenty-four hours prior to the experiments, four groups of ten fish (10 per replicate) were transferred to test chambers where the water quality was preserved. For each test parameter, the experiments were conducted for over 96 hours, in which fish mortality was observed and water physical and chemical parameters were monitored.
